Aug 30, 2016 · Ken Shirriff. 30 Aug 2016. 12 min read. Photo: INTEL. Transistors, the electronic amplifiers and switches found at the heart of everything from pocket radios to warehouse-size supercomputers, were invented in 1947. Early devices were of a type called bipolar transistors, which are still in use.

A general-purpose computer is made up of three basic functional blocks. The central processing unit (CPU), which combines arithmetic and control logic functions; a storage unit for storing programs and data; and I/O units (UART, DMA controller, timer/counters, device controllers, etc.) that interface to external devices such as monitors, printers, ...
A major step in meeting the Westinghouse engineers’ goal of putting a CPU on a single chip took place as IC manufacturing processes transitioned from bipolar to metal oxide Semiconductor (MOS) technology. By the mid-1960s, MOS enabled large scale integration (LSI) chips that could accommodate hundredsof logic gates. Designers of consumer digital pr...
Fairchild Semiconductor began the development of standardized MOS computer system building blocks in 1966. The 3804, its first complete CPU processor bit slice, featured instruction decoding, a parallel four-bit ALU, registers, full condition code generation, and the first use of an I/O bus. Designer Lee Boysel noted that it would not be considered...
Intel’s first effort in this product category, the MCS-4 Micro Computer Set, was conceived as the most efficient way of producing a set of calculator chips. Created in January 1971 by a team of logic architects and silicon engineers—Federico Faggin, Marcian (Ted) Hoff, Stanley Mazor, and Masatoshi Shima—for Japanese calculator manufacturer Busicom,...
Presented with this convoluted history, how should historians assign credit for the invention of the microprocessor? Ultimately it depends on the definition of the word as expressed by different experts in the field. According to technology analyst Nick Treddenick, “I have looked at [Boysel’s] AL1 design from the papers written about it through the...
Most historians who follow the tangled threads underlying the origins of the microprocessor conclude that it was simply an idea whose time had come. Throughout the decade of the 1960s, numerous semiconductor manufacturers contributed to an ever-increasing number of transistors that could be integrated onto a single silicon chip. Correspondingly man...

While a research manager at Intel Corp., then based in Mountain View, he realized that silicon technology had advanced to the point that, with careful engineering, a complete central processor could fit on a chip.
May 4, 2011 · Ted Hoff was employee number 12 at Intel. Working under Silicon Valley icons Robert Noyce and Gordon Moore, he helped to invent the first ever microprocessor.
Marcian Edward "Ted" Hoff Jr. (born October 28, 1937, in Rochester, New York) is one of the inventors of the microprocessor. [2] Education and work history. Hoff received a bachelor's degree in electrical engineering from the Rensselaer Polytechnic Institute in 1958.

Marcian “Ted” Hoff (PhD '62 EE), is best known as the architect of the first microprocessor. Intel’s 4004 was released in November 1971, 35 years ago this month. The history that his ingenuity helped spawn is now the subject of a new DVD, the Microprocessor Chronicles.
