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 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 ...
He began to consider whether a truly general-purpose processor could be made cheaply enough to be used in a calculator. [9] When later asked where he got the ideas for the architecture of the first microprocessor, Hoff related that Plessey , "a British tractor company", [ 10 ] had donated a minicomputer to Stanford , and he had "played with it ...
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 ]
[22] [23] IBM first used ICs in computers for the logic of the System/360 Model 85 shipped in 1969 and then made extensive use of ICs in its System/370 which began shipment in 1971. The integrated circuit enabled the development of much smaller computers. The minicomputer was a significant innovation in the 1960s and 1970s. It brought computing ...
Hitachi introduces SuperH architecture, [8] which provides the basis for ARM's Thumb instruction set. [9] 1993. Intel launches the original Pentium microprocessor, the first processor with a x86 superscalar microarchitecture. 1994. IBM introduce the first IBM mainframe models to use single-chip microprocessors as CPUs, the IBM System/390 9672 ...
The subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on the exact definition of the term "microprocessor". The earliest multi-chip microprocessors were the Four-Phase Systems AL-1 in 1969 and Garrett AiResearch MP944 in 1970, developed with multiple MOS LSI chips. [176]
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."
