The first chips that could be considered microprocessors were designed and manufactured in the late 1960s and early 1970s, including the MP944 used in the Grumman F-14 CADC. [1] Intel's 4004 of 1971 is widely regarded as the first commercial microprocessor. [2]
He was inducted into the National Inventors Hall of Fame in 1996 [17] and received the National Medal of Technology and Innovation in 2009 from President Barack Obama. He was made a Fellow of the Computer History Museum in 2009 "for his work as part of the team that developed the Intel 4004 , the world's first commercial microprocessor."
While there is disagreement over who invented the microprocessor, [2] [14] the first commercially available microprocessor was the Intel 4004, released as a single MOS LSI chip in 1971. [15] The single-chip microprocessor was made possible with the development of MOS silicon-gate technology (SGT). [ 16 ]
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60 (equivalent to $450 in 2023 [2]), it was the first commercially produced microprocessor, [3] and the first in a long line of Intel CPUs.
The Intel 4004 Microprocessor and the Silicon Gate Technology, A testimonial from Federico Faggin, designer of the 4004 and developer of its enabling technology – Federico Faggin personally gives details, history and nitty-gritty details about the Intel 4004's development and his inventions, innovations and ideas that made it all possible.
The earliest multi-chip microprocessors were the Four-Phase Systems AL1 in 1969 and Garrett AiResearch MP944 in 1970, each using several MOS LSI chips. [33] On November 15, 1971, Intel released the world's first single-chip microprocessor, the 4004, on a single MOS LSI chip.
He was employed to implement the transistor-level logic of Intel's next microprocessor, which became the Intel 8080 (conception and architecture by Federico Faggin), released in 1974. [3] Shima then developed several Intel peripheral chips, some used in the IBM PC , such as the 8259 interrupt controller , 8255 parallel port chip, 8253 timer ...
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 ...
