What are the typical application structures and application software structures of single chip micro

The MCU is generally what we call the MCU, which is generally composed of internal CPU, memory, flash and peripherals.

The single-chip microcomputer application system refers to the whole system with certain functional performance composed of the single-chip microcomputer and related peripheral circuits, embedded software, etc. according to the needs of users.

In the vernacular, it may not be professional, I hope it can help you.

What is the difference between a general-purpose microcontroller and a special microcontroller? Today is a long time to see.

Hello, I am glad to answer for you, the basic structure of a microcontroller: combinator, controller, main register. Combinator functions:

perform various arithmetic operations; Perform various logical operations and perform logic tests, such as a zero-value test or a comparison of two values. Main register function: Used to hold the address of the memory unit or IO device that the current CPU wants to access.

Controller function: take out an instruction from memory, and indicate the location of the next instruction in memory; Decode and test the instructions, and generate corresponding operation control signals to facilitate the execution of specified actions; Command and control the direction of data flow between CPU, memory, and I/O devices. Expand the scope of data application:

MCUs penetrate into all areas of life. Missile navigation device, aircraft control of various instruments sail system, computer network communication and data transmission, industrial automation car real-time control and data processing, widely used various intelligent IC cards, civil luxury car security system, video recorder, camera, automatic washing machine control, etc. There are also robots, smart meters, medical devices and various intelligent machinery in the field of automatic control.

The applications of single-chip microcomputers in life include: mobile phones, TVs, air conditioners, automatic washing machines, remote controls, etc.

Single-chip microcomputer (single-chip microcomputer) is an integrated circuit chip, which is a kind of ultra-large-scale integrated circuit technology with data processing capabilities of the first processor CPU, RAM, read-only memory ROM, a variety of IO ports and interrupt system.

Timer counter and other functions (which may also include display drive circuits, pulse width modulation circuits, analog multiplexers, AD converters and other circuits) are integrated into a silicon wafer to form a small but complete microcomputer system, which is widely used in the field of industrial control. From the 80s of the last century, from the 4-bit and 8-bit single-chip microcomputers at that time, to the current 300m high-speed single-chip microcomputer.

Combinators are composed of arithmetic & logical unit (ALU), accumulators, and registers.

The function of ALU is to perform arithmetic or logical operations on the incoming data, and input ** as two 8-bit data, one from the accumulator and the other from the data register. ALU can add, subtract, and, or, compare the size of these two data, and finally store the results in the accumulator.
