MICROPROCESSOR

• A microprocessor is the functions of a computer central processing unit on a single integrated circuit.It is multipurpose programmable device that accept data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors operate on numbers and symbols represented in the binary numeral system.Microprocessor control of system can provide implement using electro mechnical controls.Microprocessor operate on number and symbols represented in binary system.

A block diagram of internal architecture of the Z80 microprocessor ,showing the arithmatic and logic section,register file,control logic section and data lines.It has 32 bits data.It is cheap in cost.This CPU cache has the advantage of faster access than chip memory.The processor speed has increased more rapidly than external memory speed.
