A microprocessor is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components.
The microprocessor can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components and is the arithmetic control part of the microcomputer. It can form a microcomputer with memory and peripheral circuit chips.
Compared with the traditional central processing unit, the microprocessor has small, lightweight, and easy modularization advantages. The essential components are a register file, an arithmetic unit, a timing control circuit, and data and address buses.
The microprocessor is the core component of a microcomputer and a key component of various digital intelligent devices. High-end computing systems such as ultra-high-speed supercomputers and mainframe computers in the world are also built with a large number of general-purpose high-performance microprocessors.
