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
Aug 9, 2024 · In 1980, he returned to Japan as a director of the Intel Japan Design Center. In 2000, he became professor at Aizu University in Japan, and retired in 2004. Shima shares the Kyoto Prize (1997) with Hoff, Faggin, and Mazor.
May 17, 1994 · In 1970 Shima went back to Japan and worked with production of the 4004 there. He then went to work for Ricoh in their business computing department until moving to Intel where worked on improving the 8008. In 1976 he left Intel to work at Zilog on the Z80.
Masatoshi Shima was the engineer responsible for the Busicom calculator design. He came from Japan a few days after Faggin joined Intel, to check the logic design of the chip set.
Together, four engineers (Dr. Faggin, Dr. Hoff, Mr. Mazor and Dr. Shima) developed the world’s first microprocessor, the 4004. The four pioneers demonstrated that by integrating a few semiconductor chips, a microcomputer could be created which could perform a wide variety of functions.
