A microprocessor is a Computer processor computer processor which slot in the functions of a computer’s central processing unit (CPU) on a single Integrated circuit integrated circuit (IC). A microprocessor, sometimes called a logic chip. The first microprocessor was the intel 4004, introduced in 1971. A microprocessor is designed to perform arithmetic and logic operations that make use of small number holding areas called registers. It is a multipurpose, register based, clock driven, digital integrated circuit which accepts binary data as input, process it according to instructions stored in its memory, and provides results as output. Its operate on numbers and symbols represented in the binary code system. Before microprocessors, small computers had been built using racks of circuit boards with many medium and small scale integrated circuits. For a general purpose computer microprocessors are used for multimedia display, computation, text editing and communication. Some microprocessors are part of embedded systems. These embedded microprocessors provide digital control to several objects including appliances, automobiles, mobile phones and industrial process control.
