Hoff: Stop and think about what life would be like without all of these little gadgets that we have come to take for granted. Nar: Today, almost everything with a battery or power cord has a microprocessor inside. In 1968, Intel Corporation was an early entry in producing the first semiconductor memory chips. Hoff: Almost all the memory in a computer was done with little magnetic cores -- little donut-shaped pieces of ferrite that had to be strung typically by hand on these meshes of wire. Nar: In 1969, Ted Hoff was asked to help engineers from a Japanese firm transfer a multi-chip calculator design to Intel. Concerned that the chips were too complex for Intel, Hoff shared his concerns with Intel co-founder Bob Noyce. Hoff: and he said: "If you have any ideas how to simplify it, why don't you investigate them." HOFF: So that was the first thing I thought of--let's simplify the instruction set & add sub-rouine capability. Nar: Hoff's next step was to define a tiny one-chip computer, a microprocessor The contributions of Hoff, Stanley Mazor and Federico Faggin enabled this concept to go from idea to product. Mazor: I was the liaison person with the two customers in my office and they wanted to build a desktop calculator and they wanted to do it their way, and we said: No (laughs) MAZOR: so one of my principal jobs was to show them how we could do what they needed their calculator to do, and how we could do it through programming, and through the architecture of the microprocessor. Nar: Faggin led the effort to design and develop the chip, making it a reality. Faggin: I had to first develop the methodology that made possible to design random logic circuit with silicon gate technology which had never been done before. Circuits of that complexity, require a special way of doing it. Nar: The Busicom calculator was indeed produced but Intel held the rights to the chip. And the Intel 4004 became a big deal. Hoff: We probably haven't seen anything yet. Mazor: The revolution that will come is that computers will see the world and interpret objects as we interpret them. Faggin: There is no question in my mind that, it's only a question of time, when we will have, computers that go way beyond the capability of, today's, microprocessors.

Early years

Mazor was born to Jewish parents, As a youth, Mazor's family moved to California, where he attended Oakland High School from which he graduated in 1959. He enrolled in San Francisco State University (SFSU), majoring in math and studying helicopter design and construction as a hobby. Mazor met his future wife Maurine at SFSU and they wed in 1962. Around the same time, he became interested in computers and learned to program SFSU's IBM 1620 computer, taking a position as a professor's assistant and teaching other students to use the technology. Meanwhile, he continued to study computer architecture in technical manuals outside of school.

Career summary

In 1964, he became a programmer with Fairchild Semiconductor, followed by a position as computer designer in the Digital Research Department, where he co-patented "Symbol", a high-level language computer. (The "Symbol" computer was never patented as a complete unit, and the U.S. Patent Office lists only four patented sub-units: 3,643,225: Memory Control System; 3,643,227: Job Flow and Multiprocessor Operation Control System; 3,577,130: Means for Limiting Field Length of Computed Data; and 3,647,348: Hardware-Oriented Paging Control System. Mazor's name is on that last one.) In 1969, he joined the year-old Intel Corporation, and was soon assigned to work with Ted Hoff on a project to help define the architecture of a microprocessor—often dubbed a "computer-on-a-chip"—based on a concept developed earlier by Hoff. The Japanese calculator manufacturer Busicom asked Intel to complete the design and manufacture of a new set of chips. Credited along with Faggin, Hoff, and Masatoshi Shima of Busicom as co-inventor, Mazor helped define the architecture and the instruction set for the revolutionary new chip, dubbed the Intel 4004.

Although there was an initial reluctance on the part of Intel marketing to undertake the support and sale of these products to general customers, Hoff and Mazor joined Faggin, designer of the 4004 and project leader, and actively campaigned for their announcement to the industry and helped define a support strategy that the company could accept. Intel finally announced the 4004 in 1971.

After working as a computer designer for six years, Mazor moved to Brussels, Belgium where he continued to work for Intel, now as an application engineer helping customers to use the company's products. He returned to California the following year, and began teaching, first in Intel's Technical Training group, and later at Stanford University and the University of Santa Clara. Various teaching engagements took him around the world, including Stellenbosch, South Africa; Stockholm, Sweden; and Nanjing, China. In 1984, Mazor joined Silicon Compiler Systems. In 2008, Mazor was the Training Director of BEA Systems.

Publications

In 1993, then working at Synopsys, he coauthored, with Patricia Langstraat, a book on chip design language entitled A Guide to VHDL. Over the course of his career, Mazor has also published fifty articles.

Recognition

Along with his co-inventors Hoff, Faggin, and Shima, he has received numerous awards and recognitions, including the Ron Brown American Innovator Award, the 1997 Kyoto Prize, and induction into the National Inventors Hall of Fame. In 2009 the four were inducted as Fellows of the Computer History Museum "for their work as the team that developed the Intel 4004, the world's first commercial microprocessor."^[2] In 2010, Mazor and his co-inventors Hoff and Faggin, were awarded the National Medal of Technology by President Barack Obama.
