The Z80 microprocessor die, showing the main components of the chip.

A microprocessor is your personal computer processor which incorporates the functions of any computer's central control unit (CPU) on a single integrated circuit (IC),[1] or for the most part a few built-in circuits.[2] The microprocessor is a multipurpose, time clock driven, register structured, digital-integrated circuit which accepts binary data as source, processes it according to instructions stored in its storage area, and results as outcome. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors are powered by numbers and symbols displayed 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 power, increasing efficiency. Integrated circuit processors are produced in good sized quantities by highly programmed processes resulting in a low per unit cost. Single-chip processors increase dependability as there are many fewer electro-mechanical connections to fail. As microprocessor designs get better, the price tag on processing a chip (with smaller components built on a semiconductor chip the same size) generally continues the same.

Before microprocessors, small computer systems have been built using racks of circuit planks with many medium- and small-scale included circuits . Microprocessors put together this into one or a few large-scale ICs. Sustained boosts in microprocessor capacity have since rendered other forms of computer systems almost completely obsolete (see background of processing hardware), with a number of microprocessors used in everything from the tiniest embedded systems and portable devices to the most significant mainframes and supercomputers.

The 4004, developed in 1970, was the first microprocessor.
