description Masatoshi Shima Overview

Masatoshi Shima was a Japanese engineer instrumental in early microprocessor development. His work designing logic for the Intel 4004, the first commercially available microprocessor, significantly advanced computing technology. He later contributed to the Intel 8080 and Zilog Z80 projects. Shima’s innovations are particularly relevant for historians of computer science and those studying the origins of integrated circuits.

help Masatoshi Shima FAQ

What famous computer chips did Masatoshi Shima help design?

Masatoshi Shima was a key contributor to the design of the Intel 4004 microprocessor. He also helped implement the logic for other seminal chips like the Intel 8080 and the Zilog Z80.

What company did Masatoshi Shima originally work for before joining Intel?

Before his time at Intel, Shima worked as an engineer for the Japanese company Busicom. He visited Intel to collaborate on a custom chip set for his company's printing calculators.

What specific engineering task did Masatoshi Shima handle for the Intel 4004?

Shima was responsible for translating the conceptual logic into a physical layout for the microprocessor. He worked closely with Federico Faggin to complete the complex transistor-level circuit design.

Where did Masatoshi Shima go after his success at Intel?

Following his foundational work at Intel on the 4004 and 8080, Shima left to join Zilog. At Zilog, he helped design the highly successful Z80 microprocessor.
