A microprocessor is some type of computer processor which contains the functions of a computer's central control unit (CPU) on a single built-in circuit (IC),[1] or at most a few built-in circuits.[2] The microprocessor is a multipurpose, clock driven, register based mostly, digital-integrated circuit which accepts binary data as input, processes it regarding to instructions stored in its memory, and provides results as outcome. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors are powered by numbers and symbols represented in the binary numeral system.The integration of a whole CPU onto an individual chip or over a few chips greatly reduced the cost of processing electric power, increasing efficiency. Integrated circuit processors are stated in good sized quantities by highly automated processes producing a low per product cost. Single-chip processors increase consistency as there are many fewer electrical power connections to fail. As microprocessor designs progress, the price of developing a chip (with smaller components built on a semiconductor chip the same size) generally continues the same.

Before microprocessors, small computers had been built using racks of circuit boards with many medium- and small-scale integrated circuits . Microprocessors blended this into one or a few large-scale ICs. Extended increases in microprocessor capacity have since rendered other types of personal computers almost completely outdated (see background of processing hardware), with one or more microprocessors used in everything from the smallest embedded systems and portable devices to the most significant mainframes and supercomputers.
