What is the main composition of the mainframe of a microcomputer

This article mainly introduces what the mainframe of the microcomputer is mainly composed of, the introduction in the article is very detailed, has a certain reference value, interested friends must read it!

The main components of the mainframe of a microcomputer are CPU and internal memory. A complete microcomputer system includes two parts: hardware system and software system. The hardware system consists of arithmetic unit, controller, memory and various input and output devices.

Detailed introduction:

Microcomputer is referred to as "microcomputer" and "microcomputer" for short. Because it has some functions of human brain, it is also called "microcomputer". A microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal based on microprocessor, equipped with internal memory, input and output interface circuit and corresponding auxiliary circuit.

There are three levels of microcomputer system from global to local: microcomputer system, microcomputer and microprocessor (CPU). Neither a simple microprocessor nor a simple microcomputer can work independently, and only the microcomputer system is a complete information processing system, which has practical significance.

A complete microcomputer system includes two parts: hardware system and software system. The hardware system is composed of arithmetic unit, controller, memory (including memory, external memory and cache), various input and output devices, and works in "instruction-driven" mode.
