Who Invented the Microprocessor?

 Computer History Museum, discussion edited by David Laws.

The microprocessor is considered one of the most significant milestones in the history of engineering. The lack of a generally accepted definition of the term has fueled many claims about who invented the microprocessor. The original use of the word microprocessor described a computer that employed a microprogrammed architecture, a technique first described by Maurice Wilkes in 1951. Viatron Computer Systems used the term microprocessor to describe its compact System 21 machines, intended for small business use, in 1968.

Its modern meaning is an abbreviation of micro-processing unit (MPU), that is, the silicon device in a computer that performs all the essential logical operations of a computing system. Popular media often define it as a “computer on a chip.” This article describes a timeline of the early approaches aimed at integrating the main functional blocks of a computer into an ever-smaller number of microelectronic chips, culminating in the concept of the microprocessor.
