RW: This is Rob Walker. We're here today with Federico
Faggin. Thanks for having us... doing this interview.
FF: Thank you.
RW: So
you designed your first computer at 19, can you tell us about that?
FF: Yes. I finished technical high school when I was eighteen
years old and I was hired by Olivetti in Borgolombardo, near Milano, in Italy
as a technician. Actually, "assistant engineer," I think was the title.
I went through some training, about two months worth of schooling at Olivetti
to learn about transistors and digital electronics and so on, advanced digital
electronics because what I had at school was, sort of, lower level. And then
I took on the job of another engineer that was leaving and this engineer was
building a small computer and my job was to continue his work.
And basically I ended up learning on the job, my boss was teaching me a bit,
and over the course of a year I was able not only to build the thing but also
to do most of the design. In this first computer was a computer with 4,000 bytes
of memory and it was a big rack of electronics with many printed circuit boards.
As a matter of fact, I have one of the printed circuit boards that we were using
in those days. [Holding circuit board]. This is two flip-flops and it has four
transistors and all discrete components. And my computer had something like several
hundred of these boards in it. Of course, the function of that computer now is
in one chip... actually not now, now it's in a corner of one chip.
RW: It's a cell.
FF: That's
right. It's a little cell. But this was my first acquaintance with computers
and then I went back to university. I went to Padua, University of Padua, and
I studied physics because I wanted to really learn more about mathematics and
basic physics. I felt that that grounding would be much more useful to me than
doing more engineering. And so I did that, and then I went back to work again.
RW: Well, now when did you go to Fairchild?
FF: Ah,
Fairchild was in... was in early `68. But before that I was working in Italy
for SGS-Fairchild, which was partly owned by Fairchild. That's, in fact, how
I got in this country. I got here because I was sent here for supposedly a period
of six months and thirty-six years later, I'm still here. Ah, and at SGS-Fairchild
I worked on MOS technology. I basically developed their first MOS process technology,
manufacturing process technology, in '67. And I designed two commercial circuits
for SGS and then they sent me over here to come at Fairchild R&D as an exchange
program, and one of the engineers of Fairchild went to Milan: Des Fitzgerald,
you probably remember him. He used to be an engineer working in the physics department
in R&D of Fairchild.
So we had this exchange program and I started in February, as a matter of fact,
working in Palo Alto, not too far from my home now.
RW : Yes, I was over there. I started at R&D in
1966 doing ASICs, what we call ASICs, but when you think about the work that
came out of Fairchild R&D... is the seminal work...
FF: Oh, absolutely.
RW: ... of the industry today.
FF: That was the company to be in and certainly, you know,
their prime was probably in the mid 60's, but even in `68 it was still the company
to be in. I was really very happy to be here, I was happy to be in this area
and, in fact, I just had married six months before so we were really, really
very happy to be free from, you know, parents and... we were both very young
and in love and we were just, you know, having a ball here.
RW: Well now, you developed the silicon gate, the first
practical...
FF: Yes.
RW: ...usable silicon gate process.
FF: That's
correct. Yeah, that was the first project. In fact, when I joined the lab, I
was given the choice of two things to do. One was a circuit design, a shift register
using metal-gate technology. I think it was a hundred or two-hundred bit shift
register. And the other alternative that I had was to develop a process technology
using polysilicon as the gate electrode of the transistors. And I recognized
immediately the advantages of using polysilicon and I decided... I picked that
one, even if my heart was leaning more and more, even in those days, toward design.
And so, so I picked that and Tom Klein had done some prior work to show that,
in fact, the work function between the polysilicon and silicon would work out
in such a way that the threshold voltage would be lower, which was a big advantage
in those days because we could not control Qss as well as we can today. But there
was& there was no way of doing it. In fact, even etching polysilicon, it
was not understood how to do it. And so I started from scratch. I started from
the basic idea that how, you know, how could one make an integrated circuit using
polysilicon. I developed the basic architecture of the process; I developed the
etching solution for etching reliably polysilicon and, using some existing test
patterns that were there, showed that, in fact, we could produce workable transistors
within a few months after we started it.
I also invented the buried... what is called the buried
contact, which is the polysilicon to silicon contact which was& In fact,
later on, was the one that allowed us to make the microprocessor so quickly,
so soon, because it would allow to have much more dense circuitry than was possible
with metal gate. So, by April we had the basic process technology worked out
and then I designed the first integrated circuit to use the silicon gate technology,
which was the 3708. It was an 8-bit analog multiplexer using decoding logic.
It was housed in a 16-pin package and it was a product that was particularly
difficult to do in manufacturing. There was already a product called the 3705,
it was in the catalog of products of Fairchild. It was sold mostly to military
applications.
And because the "on" resistance of these
transistors had to be very low, they had to be fast, and the leakage had to be
extremely low, it was very difficult to make. And so we picked that device as
a test bed for the technology and eventually, in `69, we were in production with
that in the lab so that became the first, the first commercial silicon-gate technology
product -- integrated circuit -- to be sold.
RW: And today, essentially every integrated circuit
uses silicon gate.
FF: Today, it's basically 90% of all semiconductors use silicon-gate
technology. Derivatives, of course, of silicon-gate technology. About $90 billion
last year worth of business.
RW: Now did you get a patent on that?
FF: Yes. Tom Klein and I got a patent on that. I don't really
know how... see the idea... the basic idea was, I think, Hughes and then AT&T
had done some work also, although nobody had really been able to make workable
circuits with that idea. I didn't know anything of that. In fact, I was... I
found out later that there had been some prior work and when I joined the labs
I was told, "Hey, why don't you, you know, why don't you do a process using
polysilicon," and then that's all. And then I started from that basic information,
with no more information than that. So I found out later there was some prior
art but nobody had really been able to do it, to do it right; to do it, you know,
in a workable manner, and it's really this... it's the difference between an
idea and something that works.
RW: Had
Gordon Moore and Bob Noyce started Intel yet?
FF: No, no. They started, as a matter of fact, after I had proven
that it was working. We had& the 3708 came out already and basically they
knew that the technology was working. In fact, I suspected they were going to
use silicon-gate technology at Intel and I told... I told Bob Seeds [the manager
of the Digital Integrated Electronics department], I remember, in those days,
I said, "Hey, I have a hunch theyre going to use silicon-gate technology." And
Bob Seeds said, "Well, if they do that we're going to sue them."
RW: Which they didn't do.
FF: Yeah, which they didn't do. But I remember that I was a
boy from Italy, I didn't understand the ways of the States, so suing was something
very strange for me in those days.
[Laughs.]
RW: Well
I went to an IEEE meeting after Intel was a little over a year old where Andy
Grove was talking about their products. And he made the statement that this proved
you could move a process from Palo Alto to Mountain View in less than a year!
Which was always what we spoke about...
FF: Yeah.
RW: ... from Fairchild R&D in Palo Alto to Fairchild
production in Mountain View but he was referring to Intel...
FF: ...to Mountain View Intel...
RW: ... in Mountain View. So I think it was pretty
clear that they did take some intellectual property.
FF: Oh absolutely. There's no question about that. Of course,
you know, now Intel would sue you if you even whiffed something... but in the
origin of Intel, I mean, it's very clear that the silicon-gate technology, where
it came from... and there's no question about that. As a matter of fact, later
on Les [Vadasz] patented the idea of polysilicon to silicon contact--which was
my idea at Fairchild--and I found out in `74 that he actually had patented that
idea as Intel. [Laughs.]
RW: But then... so you decided rather than fight `em,
to join `em, so in 1970 you went to Intel.
FF: Yeah,
in 1970 I decided that I had enough of Fairchild. With Noyce and Moore leaving
and the new management team coming in, Fairchild was beginning to really have
a slow but steady decline. And also my interest was more toward design and I
was, you know, getting less and less interested in process technology, although
I managed to develop in `69, N-channel polysilicon devices. I also developed
bipolar and MOS in a single [process] -- what now is called BiCMOS -- I had early
BiCMOS devices built in those days, just the beginning of it.
And I also managed to make thin-film transistors using polysilicon material and
so it was a particularly creative period of my time and I enjoyed Fairchild Labs
but it was time for me to move on.
And so I went to my old boss, who was Vadasz. He was
my boss at Fairchild as well and he had joined Intel in& basically soon after
Intel was founded, and I called him up and I asked him if he had a job for me
because I wanted to design with silicon-gate. Fairchild still did not have a
good silicon-gate technology in production that I could use and so I decided
to leave.
And Vadasz hired me and my first job was to design
the first microprocessor.
RW: Yeah, you were doing the circuit design and Ted
Hoff did the architecture and...
FF: Ted Hoff did the architecture and I did everything else.
The logic, the circuit, the whole... and I also finished off the architecture
because the architecture had still some& few things that were not, you know& it
was not possibly complete... but it was 95% done.
So when I picked up the project, I did not work for Ted Hoff, I worked for Vadasz
and Ted Hoff used, in those days, to work for Gordon Moore, he was [in] Application
Research.
RW: Right.
FF: So Ted Hoff's job was finished with basically having developed,
having proposed the architecture of the 4000 family -- what became known as the
4000 family. In those days, it was called the "BUSICOM set," the "BUSICOM
chipset." I mean there was a... it had no names yet, when I joined Intel.
But after having finished the proposal... after having proposed the idea& [Ted
Hoff] working with Matsotoshi Shima, who was the engineer from BUSICOM, and also
working with Stan Mazor, they had developed the basic architecture of the family
and my job was to make it real.
When I got in, there was actually much less done than Vadasz had told me. I mean,
Vadasz told me that, pretty much, the design... the basic design was done and,
you know, what I had to do was to finish it up and, you know, do the layout and
do this thing, you know.
When I got in, there was nothing. I mean, there wasn't any structure... there
were a few pages of, you know, description of the thing with the instruction
set and a block diagram and that was it. That was all I got and then I was on
my own.
[Laughs.]
And I was already late six months on the project because for six months they
had not been doing anything.
RW: Well they, they didn't have a circuit designer.
FF: No, they didn't have anybody to do it, nor a logic designer.
I mean the logic design wasn't done.
RW: Well, Intel was at that time was a memory company...
FF: ...it
was a memory company. Yeah. So, in fact, I still remember that as I got in, Stan
Mazor -- Ted Hoff was away -- and Mazor gave me the specification and then he
gave a bunch of random schematics which proved to be totally useless later on.
But, you now, that's what he gave me.
So I started reading this thing and then he told me that the next day, Shima
would come from Japan to check the work that had been done during the last six
months.
RW: [Laughs.]
FF: So I went to pick up Shima at the airport with Stan Mazor.
And Shima, you know, was, of course, the customer and in a sort of broken English
was saying, "I came here to check. I'm here to check."
So fine. So when eventually we got into the lab, he says, "What... where
is the, you know... what have you done?" I said, "Well, I came here
yesterday. I haven't done anything."
"You haven`t done anything?!" You know, he was really mad at me. I
said, "I show you what I had."
And he said, "I already seen this. This is just idea. I came here to check.
There's nothing to check."
[Laughter.]
And he was really pissed. And it took me at least a week to calm him down. I
mean, he was absolutely beside himself because, basically, six months had gone
by and no work had been done. They had been promised the chipset a year from
six months before, so now we were already six months late. And Shima was irate
toward me because I was the man in charge and so, you know, so I was obviously
the culprit, and how could I have done that to them& And I could not get
it through his head that I had been hired the day before, you know. So that was
really hilarious, sort of, and eventually I calmed him down and I said, "Hey
look, if you help me, we'll get done sooner. If you want to bitch, bitch. But
if you help me well get it done," and, in fact, he had been quite helpful
throughout the process of designing the whole thing, checking in particular,
making sure that things would work in his calculator, which I have here -- I
will show you later -- so that ended up being quite a bit of help for me because
I was by myself.
And basically, I was supposed to do four chips in six months... by myself.
RW: Without computer aided design...
FF: Of course, without computer aided design. But I had good
pencils with lots of lead. [Laughs.]
RW: Well, the ah... why don't you... you have a photograph
there of the 4004...
FF: Yeah,
well, maybe, let me say a few words about the BUSICOM project because it needs
to be seen in that context. The BUSICOM project had four chips, one of which
was the first microprocessor, the 4004. There was the 4001, 4002, 4003, 4004.
The 4001 was a ROM with I/O. And it was a 2,000 bit ROM which was, in those days,
was really pushing it because also there was a lot of I/O -- input/output --
electronics around it that was programmable both at mask time, as well as by
the nature in which it was designed.
Then there was the 4002 which was a 320-bit RAM plus output [port]. There was
no input in that case, only output... output registers. And then the 4003, which
was a shift-register. It was a 10-bit shift-register, serial-in, parallel-out,
[serial-out,] static shift register so that was a very simple chip.
And then the 4004, which was a CPU. And the CPU with the instruction set that
was sort of tailored for calculator applications because that was the intention
in those days, to apply this chipset to make a variety of calculators for BUSICOM.
It was an exclusive contract for BUSICOM so it could only... BUSICOM was the
only customer. And here's the result of the effort [holding up photomicrograph
of 4004 die]. This is the world's first microprocessor. It's a chip roughly 136
square mils, 136 x 136... it's actually... it's not a square but it turns out
to be about 136 square equivalent area.
And it has about 2,300 transistors and you can see here the registers -- general
purpose registers. This is the stack for the addresses, the address counter is
over here. The instruction decoder is here, there's control logic all around
here and all around here. The timing is over... let me look at my... yeah, the
timing is on this side, and this is the arithmetic and logic unit. So this whole
thing, ten years ago [earlier], required something like several hundred of these
boards to be made and so this is the progress in ten years.
And, of course, in real size, here is the first microprocessor [holding IC chip].
It's inside here, the package is shown here... 16-pin... and in those days, 16-pins
was religion at Intel. There was& In fact, I wanted to use more pins than
sixteen because it would have been faster. We lost a lot of performance by limiting
the architecture to only 16-pins. We had to multiplex, on 4 bits, address and
data, wasting all that time. So we wasted about a factor of three in performance
in those days by a silly decision to go to 16-pins.
In fact, it took me a long time to convince my boss and, in general, Intel management,
to go to 40 pins for the 8080. The 8080 was my idea, my architecture, and that
was one of the major battles that I had to fight to get Intel to agree that 40
pins was an acceptable package size. At any rate, this is it! This is the first
microprocessor. It used to run at 750MHz [kHz] using P-channel technology so
there were two power supplies, +5 and -12. And...
RW: Not 750MHz. You mean "kilohertz."
FF: Not 750MHz or 75MHz... it was probably... the equivalent
would be more like 75 MHz because, in fact, this device could run a little faster,
you know, could run more like 1.2MHz, but because it was only for one customer,
we didn't want to lose any [speed] distribution. We were selling 750kHz, everything
that was functional.
So that corresponds to between 75 and 120MHz of today...
RW: Oh, I see.
FF: So there's about a factor of a hundred in performance between
1970, which is this time [the 4004 time], and 1995.
RW: Now,
I remember prior to even Intel being formed that at Fairchild we were working
on a similar design, a four-bit processor...
FF: Yeah.
RW: ...that would be used for a calculator...
FF: Yes...
RW: In fact, Hewlett-Packard was going to be the customer...
FF: Yeah.
RW: ...and... but we could never make the damn thing
until... we eventually did and it came out as the "PPS-25," but then
that was several years after the 4004...
FF: Yeah.
RW: But we were just limited to how much we could...
how many transistors we could get on a chip.
FF: That's correct.
RW: And
so, Intel had the hottest process around at that time and so I guess the confluence
of the technology really drove the ability to put a computer on a chip...
FF: Sure... oh absolutely...
RW: It had been a dream.
FF: Absolutely. I mean, the idea of a CPU on a chip was around
since the mid-sixties. When people realized that every few years you could take
something that was in a board like this and make it into a chip like this, and
then you put many of those [chips] in a board, and then a few years later, it's
another chip like this. You know, it didn't take much of that to go on before
people realized, "Hey, you know, a CPU that requires many boards one day
is going to be in one chip." So the idea of CPU on a chip had been advanced
since the early sixties and was talked about in the mid-sixties, so it was really
a question of when the process technology would be mature enough that you could
put enough transistors in a chip that were sufficient to create a CPU.
Well, in 1970, the technology to make microprocessors
was really available only at Intel because Intel had developed the... they had
silicon-gate and silicon-gate was the only way to do it in those days. To do
it effectively, cost effectively, because the whole idea was "let's make
this thing at a cost at which, you know, people are going to use it. If it costs
too much, people are going to use the old ways."
So the basic difficulty in those days to have microprocessors was having a process
technology that could actually do it; and then doing it. In other words, designing
it. Designing it in a manner that was economical so that, again, the minimum
number of transistors would be used to get the function done. And then producing
it. So that is the task that I performed at Intel, which was to reduce an architecture
that was done by Ted Hoff, into practice, and make it work.
And that was a job that took about eleven months of real hard work. I mean, I
worked anywhere from twelve to fourteen hours a day, partly because we were,
as I mentioned earlier, we were late before starting. Of course, I got back to
a schedule to where it would take a year to get it done. Actually, no, I got
it back to where it would take nine months to get it done, so I already lost
three of the six months and then it took two months longer than the customer
really wanted.
Certainly, I wanted to have a year. Because four chips done by hand in those
days was a tall order... to do that in less than a year.
So anyway, so that's the story behind [the microprocessor.]
I want to show you here the first product that used the first microprocessor.
And this is a calculator. This is the engineering prototype than BUSICOM used
to debug their product and you can see here& this is the printer by the way,
it's a Seiko printer, drum printer. You can see here, if I can do this without
breaking anything, you can see here the PC [printed circuit] board, it contains
the 4000 family here. Let me take a look... those are the shift-registers, by
the way, they were driving... providing the signals for the hammers of the printer
and this is the... some transistor drivers for the printer. And that was the
only sort of non-integrated portion of the calculator, the rest of it was all
done with LSI and the 4004 is this one. There were... there was one 4002 here,
another one here and the rest of them were 4001s, which are the ROMs. So the
program was contained in these ROMs, one, two, three, four, and five over here...
so five ROMs, two RAM chips, and one CPU and three shift-registers was all that
was needed to do what, in those days, was a high-end printing calculator. Of
course, now everything else...
RW: Of course, today it's now one chip and it sells
for less than a dollar.
FF: Today, yeah. All this electronics is in a very small chip
that, yes, sells for less than a dollar. So this is the... but in those days,
this was a major step forward. Although calculators were built routinely using
custom integrated circuits so, in fact, what we provided to BUSICOM in those
days was the opportunity to create, fast, a number of calculators using the same
components. So the real value of the 4000 family, in those days, was not that
it could do something that could not be done before -- as a matter of fact, that
calculator was a little more expensive than if you had done a custom circuit...
RW: Yes.
FF: ...but
you could have the next calculator done faster and, in fact, over the life that
was a short life for the company -- the company went bankrupt& but over the
two years from '70 to '72, before BUSICOM went bankrupt, they had designed a
number of calculators and a number of other products using the 4000 family.
RW: But because it's programmable, it could be used
as a controller, it could be used as anything.
FF: Of course, yeah, but in those days, though, Intel believed
that -- and Ted Hoff in particular believed that -- the 4004 was really only
good for calculators. In fact, I was the one that really pushed Intel to go into
the market with the 4000 family. Hoff believed that the 8008, which was the first
8-bit microprocessor that Intel did, was very good for, you know, a bunch of
applications and so on, and certainly was behind that, but as far as the 4004
and that family, he really was not... [he] believed that is was only good for
calculators. And I really wanted that product to be on the market and so I really
pushed Intel management.
The first thing that I did was: I developed a tester. A tester for the 4004 as
a matter of fact, and I used the 4004 as the controller of the tester and so
I could show, "Look, you know, this is not a calculator, right? I'm using
the 4004 to do a control function for the tester and it's doing the job, and
it's doing the job well." And that certainly got into the ears of Noyce
and certainly that was an important event because it turned their minds toward
the potential of the 4000 family.
And then I also pushed Noyce to get released from the exclusive agreement that
they had with BUSICOM because in those days, BUSICOM was the only company that
could use the 4000 family. And so I was in contact with Shima and I knew that
they really were hurting because of the cost they were paying for the chipset
to Intel and the company was not doing very well. And I realized that if Intel
was to give a price break to BUSICOM, they would have a chance to get released,
you know, from the exclusivity. And I proposed that to Noyce when I found out
that he was going to Japan to visit BUSICOM. Noyce apparently agreed and they
negotiated -- he and Ed Gelbach -- negotiated a deal where basically BUSICOM
released Intel from the exclusivity. So that set the stage for announcing that
year... in November of `71, announcing the 4000 family. So that's how that happened.
Then of course, after that happened, everybody agreed
that it was their idea anyway. [Laughs] Because that's the way it works. When
something works, everybody thought of it. But, in fact, very early& in early
'71, Intel sight was on the 8008 as the first microprocessor and, as you know,
that was the Datapoint engine. That's another piece of evidence that shows that
people were thinking in terms of CPU on a chip even, you know, even outside of
Intel. In other words, the 8008 was the architecture of CTC, Computer Terminal
Corporation, Datapoint terminal. Then later on, the company's name was changed
to Datapoint.
And it was basically a CPU that was supposed to be done using as few as possible
MOS chips. And back in the late... in late '69, CTC had visited Intel and Ted
Hoff had seen that that architecture was... you know, could actually fit in one
chip and so he proposed a single-chip solution for CTC and that project was started...
it was started with the name "1201." When I joined Intel in April of
1970, the project was already ongoing and Hal Feeney was designing, or beginning
to design, the 1201 which, as I said, later became the 8008. It simply was renamed
the 8008.
So, as you can see, there were already two microprocessors sort of competing
for being first in the market, even at Intel in 1970. In fact, I thought, when
I joined Intel, that I was going to be second because, you know, Hal Feeney had
to design one chip and I had four to design, so you know, guess who's going to
come out first? But then later on, Hal Feeney was moved to doing something else
and also the project, you know, was difficult and Ted Hoff was unable to really
help Hal Feeney. And so the whole thing kind of got put on ice and then Hal Feeney
was moved to work for me, helping me out with testing, test programs and the
testers for the 4000 family, toward the end of 1970. And then the project, the
1201 project, was resumed in January of 1971 and I was [put] in charge of the
project. Of course, Feeney was really the engineer who did all the detailed work
under my supervision and I helped Feeney a lot.
In fact, having done the 4004 provided the basic
foundation on how to do it because it was not clear how to do random logic using
silicon-gate, back in 1970. I mean, Intel had no experience with random logic
and nobody had done random logic with silicon-gate. You needed to do things a
bit different. For example, one of the first things that I did was to use bootstrap
[loads]. You know, in those days, you probably remember, bootstraps were very
important to get higher voltage and therefore more drive capability and being
able to withstand more threshold voltage drops in dynamic circuits. And people
thought that you couldn't do bootstraps with silicon gate without having an additional
masking layer. But I had figured out a way to do it and I had understood how
it could be done without that and so I brought that technique, that I had developed
at Fairchild, at Intel. And that was a critical element of, you now, of design
that was essential to make the 4004 work in those days, otherwise it would have
been hopelessly slow.
So, anyway, that's a long story but the 8008 ended up... the 1201/8008 ended
up being finished toward the end of 1971 and was introduced in early '72 and
it became the second microprocessor of Intel.
RW: Yes, and that started... that coincided with Wilf
shutting down my custom operation...
FF: I see!
RW: ... because people perceived that microprocessors
would take over most custom and then TTL MSI [Medium Scale Integration ICs] dropped
in price from about $5 to $1 a package and those two... those two items...
FF: Yeah.
RW: ... spelled the end of my custom career until I
founded LSI Logic in 1980.
FF: Yes, yes... yeah... As a matter of fact, Hal Feeney went
to see you guys...
RW: Yes, yes...
FF: ... back in early '71...
RW: Yes, he wanted to build a silicon breadboard...
us to build a silicon breadboard...
FF: Well, actually he wanted... you know, the idea
was to see if it could be done with Micro Mosaic, not to build a breadboard actually,
to see if it was possible to do it because we had a customer that wanted it right
away. Datapoint had vanished, but there was another customer, Seiko from Japan,
that wanted to make a programmable scientific calculator and they wanted to use
the 8008, but they were in a hurry and so, you know...
RW: And I looked at...
FF: No& it couldn't be done, I mean it was...
RW: I looked at it and I said, "No, I can't do
it with standard cells."
FF: Yeah, there was no way. I mean, it was& As it turned
out, the 8008 was about as far as it could go also with a year-later technology
because it was about 10 mils bigger on a side than the 4004 and the 4004 was
already pushing it. Although today you laugh at it, you know, but in those days,
136 mil-square chip was a big chip. [Laughs.]
RW: Well
then, did you... were you involved in the 8080?
FF: That was my idea, the 8080. The 8080 was an interesting
story because I went to... I went with Hank Smith, who used to run the marketing
-- the first marketing [manager] of the 4000 family, the MCS-4, and the 8008
-- to Europe on the summer of '71, late summer of '71, presenting& in anticipation
of the [microprocessor] announcement we were going to have at the end of November,
to talk to key customers, showing the 4004 and also talking about the 8008, that
was supposed to be available in early `72.
And I visited a bunch of customers, Phillips and... Phillips and Nixdorf stand
up in my mind, particularly Nixdorf, because Nixdorf, in Paderborn, they were
particularly obnoxious to me. I mean they were just very, very... they seemed
bitter that we had a microprocessor. I mean, they were really angry that, you
know... and they were very critical about it, you know, "Oh, it doesn't
do anything and it is bad and, you know, you should have done it this way, you
should have done it that way."
RW: Well, it wasn't as powerful as a minicomputer of
the day...
FF: Of course, of course, but there was more to it because
I think that they saw that the semiconductor industry was really, with the microprocessor,
was really emerging in a leadership position that before was the position of
computer manufacturers like, you know, Nixdorf and Siemens and IBM and so on.
So they kind of saw that and they were particularly [upset]... I could see there
was more to it than just the fact that the 8008 wasn't a particularly good architecture,
although it was OK.
On the other hand, I made treasure of some of the comments they made and so on
my return from that trip, I came up with some ideas on how to make a much better
microprocessor, which became the 8080. And I wanted to do it right away, but
Les [Vadasz] want me to... Grove and, you know, sort of the top brass at Intel
felt it was too risky to start a new microprocessor when still they had not seen
how the 4004 and 8008 were doing in the marketplace.
And so it took me a long time, it took me about nine
months of really pushing and lobbying, to finally get permission to do the 8080,
[of] which I did the whole architecture, the basic design structure. And then
I hired Shima, from Japan, to work for me to actually do the detailed work. So,
after Shima came toward the end of `72, for a few months, three or four months,
I taught him how to design, you know, and really help him along and then Shima
took off. And Shima was very good and he was, you know, he carried the rest of
the project mostly, you know, with minimal supervision, of course, I supervised
him, you know, closely, but he was mostly by himself...
RW: Hm Well, the 8080 was really the breakthrough part...
FF: The 8080 was the breakthrough part. The 8080 was the microprocessor
that made the industry and it did not escape the attention of Intel. In fact,
they changed their phone number: the last four digits became "8080" back
in `74 as a matter of fact. And, it was really the first microprocessor that
broke the performance barrier. And a lot of that was because it was in 40 pins
and it used n-channel technology instead of p-channel technology. It was a better
microprocessor, of course, than the 8008 but it was compatible with the 8008.
I wanted to maintain the machine code compatibility. And it had more registers...
it was a basically... it was a cleanup of the 8008. Particularly the interrupt
structure was quite a bit better, because the one in the 8008 was totally useless.
It was really useless.
In those days, I didn't understand interrupt structure, nor did Ted Hoff, and
the old structure was really a joke, in the case of the 8008. But later on, I
figured out what really was needed to do an effective interrupt structure, and
so the 8080 reflected that. So the 8080 immediately was adopted by the market,
immediately opened up all kinds of applications that before were only suggested
by the 4004 and by the 8008. And it was just the beginning of the microprocessor
revolution.
RW: I, I remember being with Gordon Moore when the...
it was announced, I think National announced, that they were licensing Signetics...
FF: Hm
RW: ... with the 8080, which meant that there were
something like twelve or fourteen suppliers of the 8080 and Gordon was really
upset...
FF: Yeah.
RW: ... and I really think that was the start of the
real protection
FF: Yes.
RW: ... attempts to really protect the architecture...
FF: Yes.
RW: ... from others.
FF: Hm ...
RW: Because everybody copied the 8080--legally.
FF: Oh yeah. Absolutely. Yeah, including the Russians, I found
out, many, many years later. [Laughs] But another thing that the 8080 did was
that it began to really create the substance behind the movement that was happening
among universities and advanced industries, the movement of young people in the
computer clubs, as you remember, toward the microprocessor and this microelectronics
revolution that was happening. And out of that milieu, the personal computer
came out, as you remember.
RW: Altair.
FF: Altair and MITS and those kind of, you know, those kind
of machines that were 8080-based. And that was the beginning of the revolution
that we're still in...
RW: Also Microsoft, Bill Gates' first hardware...
FF: Yeah, Bill Gates first BASIC program was based on... was
for the 8080. So, anyway, that's it. Yeah, the 8080 was really, in a way, was
at Intel, was my biggest contribution from a business point of view. From a,
you know& from an empowering point of view, my biggest contribution was,
of course, the 4004. But the 8080 was the one that created the business.
RW: Now, were you involved with the 8086?
FF: No. I had left already to start Zilog.
RW: Were you involved with the 432?
FF: No.
RW: That was a...
FF: Those were all the Intel response to Zilog.
RW: Hm
FF: Yeah.
RW: Well, the 432, which is a 32-bit microprocessor,
was to be the new architecture...
FF: Sure.
RW: ...and... was an utter failure... because it was
too slow.
FF: Yes.
RW: It was much too slow and too expensive. And so
I was just arriving at Intel about this time...
FF: Yup.
RW: And the 8086 then was clobbered together very quickly.
FF: Yes.
RW: And was a 16-bit 8080.
FF: Hm
RW: And it would run code...
FF: Yeah.
RW: ... and that was its strength but it was also its
weakness...
FF: Yup.
RW: ... because it was perceived as, correctly, as
what it was... and it still contained artifacts ...
FF: Yeah.
RW: ... from the 8008...
FF: Yup.
RW: ... as opposed to the 6800 which was a clean sheet
of paper design.
FF: Yes.
RW: And, in fact, there
were two instructions in the 8086 that were designed for compatibility with the
8080, which were in the initial datasheets which we then took out during Operation
CRUSH to... so that people wouldn't perceive it as a simple extension... and
we needed to reposition it as a leadership kind of product... Well
anyway, in `74 you started Zilog?
FF: Yes.
RW: What motivated you to start a company?
FF: Well, in Silicon Valley, you know, you have to start a company
or else your manhood is going to be questioned right? Well, seriously, it was
not one reason, there were several reasons. Among them, I had worked very hard
at Intel for almost five years and I had grown professionally quite a lot. In
fact, by the time I left, I had eighty people in my department. I had more than
half of the overall R&D of Intel, which at that point was already a large
company. It was about... in `74 they did about $135 million of revenues which
was a lot in those days.
So, I had more than half of the R&D of Intel reporting to me. But, you know,
I did not have the satisfaction that I was expecting -- economical satisfaction
-- by not having been one of the early guys, I did not have a lot of stock of
the company. I had, you know, a reasonable amount of stock but not very much.
And the company was getting too big for my taste and it was getting a little
too [stifling]... Andy [Grove] was beginning to become the man in charge and
there were sign-up sheets where you had to sign-up if youd arrive after eight
o'clock, and the environment was no longer the environment that I really liked
to be part of.
So I decided that it was time for me to go, time for me to leave, that I could
start a company and work as hard and have a lot more satisfaction and having
an environment that would be much more to my liking as opposed to having to sort
of, you know, to be& I felt like you were subjugated there. So that's how
I did it.
RW: Well, I noticed that change at Intel in the culture.
It used to be that when Noyce was very active in the company, there would be
a meeting and Andy Grove would start off on one of his diatribes and Noyce would
say, "Andy, shut-up." And that was sort of the end of it. So he was
able to hold him in check and then as Noyce semi-retired and became vice-chairman,
a lot of the decency went out of the company. Because Noyce and Moore are just
such... Noyce was and Moore is.. such gentlemen and such, you know, brilliant
but people... wonderful people that you would just love to be around. Gordon
Moore never says anything dumb. I don't know if you noticed that.
FF: Yeah.
RW: He doesn't say much but whatever he says is either
very funny or...
FF: ... very cogent.
RW: ... right on the mark. He will sit through a meeting
and not say anything and then he'll make, you know, one comment which just sums
it right up. And I really... I really appreciated that.
Well anyway, so you started Zilog in '74.
FF: Yeah, at the end of `74, yeah.
RW: And there was no venture capital money to speak
of in those days, was there?
FF: No. The industry was just... had entered a recession, as
you remember. In fact, that recession lasted for most of 1975 and venture capital
had disappeared from the scene after having overdone it in the late sixties.
As you remember, in the late sixties, there were a
rash of electronics companies that had started. Typically things go in cycles
and that was a trough of a cycle. But we were lucky enough -- and I say "we",
because I started the company with one of the managers that worked for me at
Intel, Ralph Ungerman -- so he and I were the co-founders of Zilog. And when
we began to decide what we were going to do and so on, it was about the same
time that we got a phone call from Exxon Enterprises. Exxon, the oil company,
had a venture capital subsidiary that was playing in the venture capital... was
interested in creating a new possible business for Exxon Corporation for the
year 2000, and they had recognized information technology as one of the major
technologies that could give the momentum needed for... to have something that
was commensurate with the oil business.
And there was an article that appeared in Electronics News about "Faggin
and Ungerman leaving Intel to start their own firm," and it caught the eye
of someone at Exxon Enterprises, so I got a call. And they asked me if I was
interested in some money and I said, "Well, not really, I mean, we still
haven't figured out what we want to do but, you know, if you come around in the
area, give us a call and we'll... I certainly would like to chat." (Laughs)
I didn't know that that was probably the right way to attract Exxon Enterprises& At
any rate, they showed up two weeks later and by that time we had already, you
know... we had a more clear idea what we wanted to do. At that time, what I wanted
to do was a single-chip microcontroller -- what later became the Z8 of Zilog.
And so we described what we were interested in doing and so on and we started
the dialog that ended up in their investing in the company in June of `75. So
it took about six or seven months of negotiation and back and forth, but eventually
they invested in the company. They put half a million dollars in Zilog, which
turns out to have been 5% of the total venture capital investment in 1975 in
this country. Only $10 million were invested by venture capital in that year...
that's what I read in statistics. Compared to, I don't know, probably a couple
of billion dollars last year.
So we started with that money and, in fact, we were in the market having spent
about $400,000 of that money, having developed the Z80 microprocessor, the development
system, and all the software required to really bring to bear our new product
offering. In those days you could do a lot more with $400,000 than you can do
today.
RW: Hm ... Well, you didn't have to build your own
fab.
FF: No. We didn't have to build our own fab, but, you now, even
for a design team developing a system, basically a computer system, all the software,
and a chip that was state of the art in those days, it was still a very small
amount of money.
RW: What was the reaction at Intel when you left? You
said you were...
FF: Well, they were not pleased to say the least, they certainly
valued my presence but, of course, you know, I was pretty set to go and there
was nothing they could say or do that would change my mind. Andy [Grove] even...
you know... when I left... when I had my sort of "exit interview,"& No
actually, he was still trying to make me stay, he intimated that I would leave
no heritage to my children if I leave Intel... [Laughs] So it was an interesting
kind of a conversation.
But my mind was on creating a microprocessor company. Intel, still in '74, was
a memory company. Microprocessors always were taking second... second best...
and I felt not appreciated, frankly, at Intel. Maybe they did appreciate me but
they were certainly not demonstrating that. Although I got promotions, in fact,
what I did, I ended up working more for them and doing more for them. So it was
not the kind of environment that I wanted to stick around with. There was no
way that they could dissuade me to leave and Gordon tried also... but I was pretty
set and that was it.
RW: Well, the Z80 was an immediate success.
FF: Yes, it was. The Z80, believe it or not, is still in high-volume
production today. It's one of the few products that is still enduring... I understand
that over a billion Z80s have been built already.
RW: Well, it's a cell as well, or a megacell.
FF: It's a megacell. Now, of course, you hardly buy a Z80 by
itself. You buy it as part of an integrated solution, but I would guess that
even today there are probably thirty or forty or fifty million units, you know,
built a year by many sources. But it was recognized very early that it was going
to overcome the 8080. In fact, I have here& Looking over my old stuff, I
found this cartoon. It was on a German magazine and it shows the Z80 conquering
the bastion of the 8080, and on the background there are the Exxon tanks and
oil towers... [Laughs] It's kind of an interesting portrayal of what really was
going on in '76-77. The Z80 was the dominant microprocessor and had taken the
market by storm.
As I said, still today, it's a major seller. In fact, you have a picture here
of the Z80 -- thank you -- that shows the layout of the Z80 and you can see that...
this, of course, is a hand-made design like the 4004 was. But you can see the
difference in complexity. The Z80 was about ten times more transistors, more
than the... ah, no, sorry, five, six times more transistors than the 4004, five
years later. And you can see that the 4004 is more like a portion of it. So,
it was a sophisticated microprocessor for those days. Of course, today it's a
joke, it's a little thing compared to a Pentium or, god forbid, the P6 and what
have you.
But, of course, there is a time for everything and in those days this was the
best that could be done. This layout was done all by hand and I actually drew
with my own hands --two-thirds of this. So this is a...
RW: Don't try that with two million transistors!
[Laughter.]
FF: Of course, it's impossible today. Without computers you
couldn't design the chips that technology can build these days.
RW: Well, then there was the Z8000...
FF: Yeah, then there was the Z8 and then the Z8000. The Z8 was
built& Right after we finished the Z80, we started the Z8 project, and a
few months after that the Z8000. And the Z8000 was a 16/32-bit microprocessor
that was supposed to really create the new wave of the industry. And it almost
made it but not quite... [Laughs.]
RW: Well, yes, and I was at Intel at that time and
the 6800 and the Z8000...
FF: Yup. The 68000 you mean?
RW: The Z8.
FF: No, the 68000.
RW: 68000, yes, I'm sorry, and the Z8000 struck fear
into the hearts of Intel because the "great leap forward," the 432,
was an utter failure and the 8086 had been clobbered together and was generally
perceived as a poor third in... quality and performance.
FF: Well, in fact, even the chip size of the Z8000 was less
than the 8086. It was actually a very, very cost-effective microprocessor. It
was much smaller than the 68000, for example, in terms of chip area so it could
be produced... [It was] much more producible. But as history showed, that was
not enough. There were other forces playing in the marketplace in those days
and whatever happened...
RW: What is your take on the decision of IBM to use
the 8086? I've heard so many different stories...
FF: Yeah, well one factor which is not recognized at all because,
of course, things tend to be forgotten and not seen in the proper perspective,
is that a lot of the decision of IBM to go with Intel was a political decision,
because of Exxon. Exxon had declared war, basically, to IBM. As you remember
in '78, '79, Exxon went out of the closet parading their companies: Vydec, Qyx,
Qwip and Zilog on their ads on the Wall Street Journal and Business Week and
so on, about the foray of Exxon Enterprises and Exxon Corporation into the information
age, and information business. You know, sort of, "Watch out, IBM, here
we come," and here are point of attacks into your business.
And IBM wasn't going to give business to Zilog. In fact, they had an internal
edict not to use Zilog products because of the affiliation with Exxon. So we
basically were not in the running because of political reasons, and that is not
understood. Intel, in fact, they did not think... they didnt know they were going
to get the IBM order but, in fact, they got it because there was no other way.
It was, you know, either Motorola -- Motorola was too risky, the chip was too
big, it was too new, there was not enough history that it could be producible
in volume -- or Intel, because Zilog was not even to be counted.
RW: Well I also heard that the 68000 was too powerful
and would have impinged on the minicomputer business of IBM's, so that they felt
using the 8088, which is kind of crippled, that it wouldn't be too powerful.
FF: Well, but also there were [other] issues... you now, a decision
is never made because of one reason, right, in general? There were other issues
like availability of peripheral components. That's why they used the 8088 instead
of the 8086, early on, because Intel was not ready with all these 16-bit peripherals
anyway, so they had to use 8-bit peripherals which were already available. Motorola
had the big mother,but it didn't have the peripheral components required, so
there wasn't enough to build a computer with just& with the 68000. And so
that's another of many reasons why IBM presumably went with Intel. Of course,
you should ask them... [Laughs.]
Although many of the people that were involved are probably gone, god knows where,
even at IBM and so& And the main guy died in an accident...
RW: In a plane accident.
FF: Yeah, that's right.
RW: Well, there was at that time... there was a group
of salesmen, salespeople came to Intel management and said, "We are in serious,
serious trouble," so there was started something called "Operation
CRUSH," and the idea was if we could somehow get the 68000, the Z8000 would
be crushed between...
FF: Yup, between, yup.
RW: And there was all sorts of various schemes used
in Operation CRUSH... promotions and ads and so many things. But what really
proved to be the most effective was Bob Noyce going out and laying out the future
of the x86, the 186, the 286 and so while the 8086 wasn't very much, frankly,
customers like Olivetti... I know he turned Olivetti around... they saw this
road map into the future which would lead to a leadership...compatible... program
compatible leadership position and that and then of course the IBM decision swung...
FF: Yeah, that was it! I mean, the IBM decision was the "crush." [Laughs.]
RW : Yeah. It would be interesting to speculate had
they chosen something else. What would Intel be today? A much smaller company
I would think...
FF: Absolutely. Or had we had different investors? Had I been
a little more experienced in [running a company.] You know, instead of being
32 years old, if I had been 40 years old when I started Zilog, or something...
but who cares? The way things went& They went the way they went!
RW: Well then, eventually you left Zilog to start yet
another company. What was your motivation to do that
FF: Ah, yeah. Well, the motivation was that I could see no
way to succeed with Exxon, basically. As I mentioned earlier, Exxon decided --
I think they had decided all along they were going to do this, but they certainly
did not tell me that -- they decided to go after IBM and to create this huge
empire in information [technology] of which Zilog was a piece of it. And that
was not what I intended. I mean, what I intended was to have a company that would
go public, like any other company in Silicon Valley, and be dedicated to one
thing, which was microprocessors. But because Exxon had the majority of the stock
[they were in control]... In fact, they were the only investor in the company
and they wanted to stay that way from very early on, and I did not... and that's
one area of inexperience on my part.
I saw some level of danger in that [having a sole investor] but I sort of wanted
to believe that they were going to honor the desire of the founders to go public,
but it turned out not to be the case. So, I grew very tired of that situation.
I tried very hard to have them sell their interest in Zilog to other companies
for which Zilog was much more of a fit. But they wouldn't hear of it and so,
after a couple of years of trying, I said, "That's it!" I mean, I was
spending more time in New York than I was spending in the marketplace. I was
basically fighting Exxon, instead of fighting the war out there. And that is
how also Intel got it easy, because of this internal situation at Zilog that
had gotten very difficult to manage.
RW: Similar to Shlumberger's acquisition of Fairchild.
You know, destructive.
FF: I would say that it's one of many examples. In fact, look
at United Technologies and Mostek. They managed to destroy the whole company.
Honeywell and Synertek: they destroyed that company. Shlumberger and Fairchild:
they destroyed that company. And I have to say that I'm actually proud that Exxon
did not destroy Zilog, because Zilog is still alive and kicking and is the only
company that has survived this [onslaught]... from the Exxon empire. Exxon had
started at least two dozen companies. They managed to destroy every single one
of them.
RW: Yes.
FF: And Zilog is the only one that is still alive and still
doing products which are Z80s and Z8s, which was the early stuff that I did when
the company started. So I feel actually quite good about that.
RW: So what was your next company?
FF: The next company was called Cygnet Technologies, and the
idea behind that company was to create a voice and data workstation for the manager,
typically, because the manager is the person that communicates and wants data,
text and voice at his desk, by developing the other half of the voice and data
workstation, which was the communication portion. So we developed what was called
the "communication co-system," which was basically, in appearance,
like a telephone, an intelligent telephone, connected with the personal computer,
and the combination of the two would give an environment which was [both] a communication
environment and a computation environment.
For example, I could call you with the co-system in the PC, push a button, and
transfer to your PC the screen that I had in my PC, now both of us could talk
about what I had in my screen. I could also, for example, create electronic mail,
send it to a number of people in the world by timing the delivery that electronic
mail would be sent. And the mail would be sent automatically by the co-system
using commercial phone lines directly to your co-system.
So you would have a light on in your PC/co-system combination telling you that
youve got mail, and then you would read the mail, and so on. So, it was electronic
mail without a central host computer, done directly, managed directly by each
station. It was a very innovative product, but it did not go. Basically, we sold
5,000 systems the first year -- we needed to sell about 15,000 to really take
off. And it was a pity because it was a good product, but we ended up introducing
the product just a few months after the AT&T was, you know, [broken up]& the
de-regulation of the telecommunication industry. Everybody was confused. There
were people that did not want to buy anything that was telecommunication. That
was early `84 and so there was a lot of foot-dragging by the people -- by our
market -- because we needed to sell that [product] as a system and so we needed
to sell it to, basically, the communication guru of a company, or czar of a company,
and [those] people did not want to talk to us, basically.
RW: Now here in 1995, this is just starting to catch
on. So you were ten years ahead.
FF: Yeah. But, of course, you know, it doesn't give you any
good feeling to be ten years ahead. The idea is to be just right on time... At
any rate, the product is still in use in many of the networks that were built
with our product. [People] are still using it today because they find it very
useful, very useful... It had, for example, all the software for keeping your
calendar. For example, it would beep you when you had an appointment. Suppose
the entry said "Call Rob," then I would simply push the button, and
it would call you automatically because the calendar was linked with the directory
and it would call you immediately.
RW: Just like today.
FF: Yeah, just like you can do today, and this was in '84. So
it was a very advanced product for the day, both in hardware and software. But,
as I said, it was too early and... We almost made it, but not quite. We just
did not get into the self-regenerative, you know& You have to have enough
business that you begin to pay the bills and get enough left over to create the
next product, and we quite not made it to even pay the bills, so we basically
ended up having to sell the company. The company was sold and I started a new
company.
RW: So, in '86 you started your third company.
FF: Yes, called "Synaptics." And this company was
from the very beginning, intended to be very different than my prior two experiences.
The idea was to develop a basic technology first, and then take it from there
and go to market. But the first six years of the company, myself and my partner,
which is Professor Carver Mead of Caltech, focused our attention to developing
basic technology for pattern recognition.
Well, Synaptics' idea was to combine together two emerging technologies that
were just beginning. One was neural networks and the other one was adaptive analog
VLSI. Let me say a few words about those technologies. Neural networks are basically
structures similar to the biological neurons that we have in our head, that are
appropriate to do tasks that are very difficult for computers, like pattern recognition,
speech recognition and writing recognition. All those very difficult tasks which
AI, Artificial Intelligence, had promised they would solve "next year," and
they had kept to promise, but never delivered.
RW: It's always "next year."
FF: It's always a promise. So we decided that perhaps there
is a way, now that sufficient knowledge existed on -- although very primitive
still -- how the brain processes information that perhaps, if we use structures
which we know work when it comes to pattern recognition -- because we can recognize
handwriting, and we can certainly recognize complex objects and faces and speech
-- maybe there is a chance.
The other thing was that, to implement that structure, we needed a technology
that was much more computationally dense that digital, and also much closer to
the sensory side, which is also analog. And that was the work that Carver Mead
had done at Caltech with his silicon retina, his silicon cochlea, and so on.
And I felt that that technology combined with neural networks could provide a
uniqueness for us to go after that market.
But, of course, we didn't know. Both of us didn't know what could be done because
the things that could be done in '86, when I started this company, were very
primitive things. Basically we could solve toy problems, we couldn't solve real
problems. But six years later, with just four or five bright young kids from
university, just right out of university, we had enough technology that we could
begin to solve real problems and so we started working on our first product which
was introduced about six months ago, by Fall Comdex last year, which we call
the "Touch Pad."
And here is our product. [Picking up touchpad.] It's
basically a touch-sensing pad that recognizes the position of the finger and
also the pressure of the finger. This is on one side. On the other side, of course,
is the electronics that controls that. There's a chip that we have developed
which is a mixed-signal device. Analog because, you know, capacitances are analog
entities. And then digital on the other side, because computers are digital.
So you need both technologies. You need to convert human-generated signals which
are analog and continuous into digital which are the signals the computers understand.
There is a microcontroller here which is about a Z80 kind of machine. It's not
a Z80 but it's that kind of class machine, with firmware which is firmware we
have developed to do this thing. And basically with this device, you have X,
Y and Z coordinates, both absolute and relative, so it performs both as a pressure-sensitive
tablet as well as a pointing device. And the first target market is to replace
trackballs and track points in notebook computers. And we have been already quite
successful. We have already a dozen companies that have adopted these and they're
just coming out in the market right now.
With this pad, you can move your finger and just tap. And basically you have
moved the cursor and activated the icon, the window, whatever you want to do.
You can double-tap, you can click-and-drag, you can do gestures on it, you don't
need any buttons. And, of course, if you are in tablet mode, you can write with
your finger or with a pen. We have a special pen which you can [use to] write
on it.
For example, you could create a fax and then you sign directly on this pad so
that now you can send the fax with your fax/modem with both the text and your
signature captured by this device.
You can, you know... We have a brush that you can [use to] paint on it. And the
more you press the brush, the bigger the area of contact and therefore, the wider
the brush stroke, so that you can actually paint with an object like this. Of
course, if you want to paint seriously, you need something larger than this.
This is just for the, you know& for basically, a pointing device and also
as an entry device. Like, in the Far East, people are very excited about this
because you can write Chinese characters on it...
RW: Kanji...
FF: And you write one character at a time anyway, so this is
all you need for that purpose. So, this is the first application of the neural
network and neural system technology that we have developed, and also the hardware
technology that we have developed because this device is adaptive. In other words,
it tracks the user. If you use this little finger, of course, it's different
than if you use this large finger, and so on. And so, it adapts to the user.
It does collective computation and it does parallel computation in order to minimize
the effect of noise, because, you know, in your finger you have about 80 volts
at 60Hz, if you're in a room like this and you can only sense millivolts to sense
[measure] capacitances. And so, you basically have a noise problem which is not
insignificant and so only through techniques of parallel computation and collective
computation can we get reliable signals.
So this is an example of a technology that we have developed. We have much more
sophisticated technology, as technology goes. For example, in recognition, image
recognition, where you can recognize faces or hands. You can tell where the hand
is in a complex picture, like a picture you're taking right now, with background
things moving, we can tell where the hand is, and whether the hand is closed
or open, with high accuracy.
We also work in sound and handwriting recognition.
We have a handwriting recognition software now for pen entry which is a factor
of five better than the best in the business, using neural network technology.
So, the fruits of this long labor are beginning to come due now. The harvest
is coming. So we're quite excited about it and the company is just taking off
and we should be profitable in a few months and we're, you know, we're on our
way.
RW: It's very rare that a startup company can have
that long a time horizon.
FF: Yes. I think that without the pedigree of Carver Mead and
myself it would have been impossible, you know. Venture capital [people] are
not patient guys, as you know. But we told them early on, "Look, we won't
spend a lot of money, but it will take time," and we ended up building all
this technology, for which we have over forty patents, building our first product,
and all the technology that we have behind, which you know, I have no time to
explain, with less than $7 million. And we got another round of financing basically,
after the announcement of the first product, of this touchpad.
RW: So how many VCs [Venture Capitalists] do you have?
FF: Ah, we have four, five VCs.
RW: They're all local?
FF: Yeah. We have Kleiner-Perkins, TVI, Sprout, Delphi BioVentures,
and Oak Partners. In the last round of financing, National Semiconductor came
in as a major partner because we made an alliance as well. So now we also have
a business partner as well.
RW: And will they fab the parts for you?
FF: If necessary. Right now we're using external foundries,
but certainly a lot of the reason for this alliance is the manufacturing muscle
that they can bring to bear on this. But they like our technology. We have a
number of projects that we are working together with, where they can develop
products around the basic technology that is embodied here and other technology
that we are not disclosing at this point. So, they themselves are going to be
able to develop a number of new products that are enabled by our technology and
that's good. And we are really working very closely together and it's a good
relationship.
RW: Well, you started three companies, now. What does
it take to be an entrepreneur? I mean, what qualities?
FF: Well, first, lots of physical strength. [Laughs.] You have
to have many qualities. The most important one, I would think, is the desire
to create a new company. In other words, just the bare desire of doing something
new in terms of organizational structure; something that goes after a specific
opportunity in the marketplace; some idea about a culture that you want in the
company: This sort of Gestalt of what the company is going to be and the desire
to create this thing. That is the most important aspect of an entrepreneur. Because
it's almost like creating your own family, a new family, you know. You leave
a place and you say, "OK, I'll create a new nest over here." And you
have to have an image in your head of what you want. The type of people that
you want...
RW: You get to... you don't have to repeat the mistakes.
FF: Of course, you get to do it better the next time, right?
The other thing is that you have to have, and I was not completely joking earlier,
you have to have a lot of strength, emotional strength and physical strength
because the early years of a company are fun, but they're also hard work.
RW: A lot of hours...
FF: Lots of hours. And you have to have also a family which
is quite supportive of what you're doing, and I'm actually quite happy that my
wife has been always supporting me. But certainly one sacrifice that I had to
make -- I also had to make, but it was my choice, it wasn't her choice -- is
to, you know, not to be at home very much. And so my children could have stand
seeing me more often, so that is not something that is good but it goes with
the territory. So, without a family which is supportive, you know, one would
find himself either divorced or would find himself in a trap, where one could
not dedicate the energy to work [while] at the same time having been unhappy,
in an unhappy family. So that is an aspect that seldom goes acknowledged, but
I think is important to acknowledge because certainly my kids have been very
important. My wife, Elvia, was very supportive of me, and has endured a lot loneliness
because of that.
RW: I hate to travel.
FF: Yeah.
RW: That's what... that's my big problem. I've never
been a CEO, never wanted to, because you have to be like the president of the
United States. You have to be not only a manager and a leader but then you have
symbolic things... and calling on customers...I just didn't care for that.
FF: It's a very demanding job because it demands... You have
to be good just about everywhere. You cannot be a C, a C- student, in any subject.
I mean, you have to be an A or a B student everywhere, and that sometimes is
difficult because the world we live in is very complex. You have to be very good
in technology, you have to be very good in marketing and sales, you have to be
very good in manufacturing, you have to be very good in finance, you have to
know how to present yourself, you have to be a good speaker, a good charismatic
figure, and all that is not easy to do.
RW: Yeah. Well, you also have to be prepared to fail.
FF: And that's harder to do. [Laughs.]
RW: Are the Japanese... not prepared to fail? ...
FF: Most people are not prepared to fail. That goes with the
territory. You try new things, you can fail.
RW: Well, that's why... one of reasons there are so
few Japanese start-ups, I think... Well, thank you Federico, this has been great
fun.
FF: Yeah, thank you. I really appreciate going back to the
old days. I still remember the days of Fairchild with the big computer clicking
on the raised floor and doing not much more work than actually a Z80 was doing
twenty years ago.
RW: It was an IBM 360/44 and it was about 0.7 MIPS...
FF: Yeah, unbelievable. I still remember punching cards and
feeding this card reader, and then fighting every minute with that stupid machine,
because, you know, the human interface in those days was so awful.
RW: Yeah.
FF: And now we can begin to, you know, with this thing [trackpad]
and with neural networks, we can begin to create human interfaces that are like
humans. In other words, here I'm just touching [touching trackpad]... I'm touching
a machine, basically. I'm brushing lightly on the machine like you would touch
skin, and we have means of machines looking at me and recognizing me, recognizing
if I smile, if I frown. And we have means to recognize, soon, voice, and so on.
Soon machines will be truly anthropomorphic. They will be able to, you know,
to communicate through sensory modalities that in the past were not even conceived
possible.
RW: Maybe real people will be able to program their
VCRs?
FF: Absolutely, in fact, I kid you not, one of the applications
that National is going after is a remote [for] television where you basically
hold something like that and you move your finger and you basically, with a graphic
user interface, you do whatever you need to do, you just do that... this kind
of movement.
RW: Well I have to get out my... I don't record that
much on my VCR. I have to get out my manual...
FF: Yeah.
RW: ...and it takes me about ten minutes.
FF: Anything that has more than fifteen buttons, you know, needs
a graphic user interface. [Laughs.]
RW: All right, well thanks, Federico.
FF: Thanks.
