The so-called Bus (Bus) refers to the common data channel that transmits information between computer devices and devices. The bus is a communication line connecting a variety of devices in the computer hardware system, and an important feature of it is that it is shared by all devices on the bus, and a variety of devices in the computer system can be connected to the bus. If it is a special signal connection between two devices or devices, it cannot be called a bus.

The bus in microcomputer is divided into three categories: data bus, address bus and control bus. The number of data buses, address buses, and control buses of different CPU chips may be different.

The data bus DB is used to transmit data information and is bidirectional. The CPU can either read data from memory or input devices through DB, or send internal data to memory or output devices through DB. The width of the DB determines the number of bits of data exchanged each time between the CPU and the rest of the computer.

The address bus AB is used to transmit the address information sent by the CPU and is unidirectional. The purpose of sending address information is to identify memory units or I/O devices that exchange information with the CPU. Memory is accessed by address, so each storage unit has a fixed address, to access any unit in 1MB memory, you need to give 1M addresses, that is, you need 20 bit addresses (220=1M). Therefore, the width of the address bus determines the maximum addressing capability of the CPU.

The control bus CB is used to transmit control signals, timing signals and status information. Some of these messages are sent by the CPU to memory or external devices, and some are sent by memory or external devices to the CPU. Obviously, the information transmission direction of each line in CB is certain and one-way, but as a whole it is two-way. Therefore, in various structural block diagrams, where the control bus CB is involved, it is represented by a two-way line.

The performance of the bus directly affects the performance of the whole system, and the development of any system and peripheral modules must comply with the bus specifications adopted. Bus technology is developing and perfecting with the improvement of microcomputer structure.
