Masatoshi Shima (嶋 正利, Shima Masatoshi, born August 22, 1943, Shizuoka) is a Japanese electronics engineer. He was one of the architects of the world's first microprocessor, the Intel 4004. In 1968, Shima worked for Busicom in Japan, and did the logic design for a specialized CPU to be translated into
Design began in April 1970 under the direction of Faggin, aided by Masatoshi Shima, who contributed to the architecture and later to the logic design. The first delivery of a fully operational 4004 was in March 1971 to Busicom for its 141-PF printing calculator engineering prototype (now displayed in the Computer History Museum in Mountain View ...

Aug 9, 2024 · Following Marcian "Ted" Hoff's initial concept, Shima, Hoff, and Mazor jointly defined the functional specifications of the new chip, called the Intel 4004, and now known as a microprocessor. Shima worked on the 4004's logic design, logic simulation, and test program generation.
Jul 2, 2018 · The first of the four engineers is Masatoshi Shima, who worked for Japanese office calculator company Busicom, which wanted to create a new computerized calculator. In April 1969, Busicom and Intel signed a provisional agreement for Intel to develop a custom set of chips for the calculator.
That programmable chip, later known as the Intel 4004, became the first general-purpose microprocessor. Hoff, Federico Faggin (who took over design leadership from Hoff) and Stan Mazor at Intel, along with Masatoshi Shima from Busicom, all contributed to making the ambitious concept a reality.
