One of the most important developments of the last half of the 20th century has been the microprocessor. It is found in virtually every automobile, medical device, and computer in the modern world. From its inception in 1969, the microprocessor industry has grown to hundreds of millions of units per year.

In the late 1960s, many articles had discussed the possibility of a computer on a chip. However, all concluded that the integrated circuit technology was not yet ready. Ted Hoff was the first to recognize that Intel's new silicon-gated MOS technology might make a single-chip CPU possible if a sufficiently simple architecture could be developed. Hoff developed such an architecture with just over 2000 transistors.

In 1969, the Japanese calculator manufacturer Busicom asked Intel to complete the design and manufacture of a new set of chips. Ted Hoff was assigned to work with Busicom's engineers. Hoff realized that the Busicom's 12-chip design -- separate chips for keyboard scanning, display control, printer control, and other functions -- could not meet the cost objectives for the project. He proposed an alternate architecture in which a single-chip general-purpose computer central processor (CPU) would be programmed to perform most of the calculator functions. Busicom accepted the Intel proposal.

Further refinements in architecture and logic design were made by Stanley Mazor and Federico Faggin and the chip was brought to silicon reality by Faggin. The first working CPU was delivered to Busicom in February, 1971.
