This article will explain in detail what the microcomputer bus is mainly composed of in the computer. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Microcomputer bus is mainly composed of data bus, address bus and control bus; microcomputer bus is the channel for transmitting information between computer modules, and bus technology occupies a very important position in the whole computer system. Its position in the microcomputer is equivalent to the traffic and communication network in the modern city.

The bus of microcomputer is generally composed of data bus, address bus and control bus.

Microcomputer bus is the channel for transmitting information between computer modules. Bus technology occupies a very important position in the whole computer system, and its position in microcomputer is equivalent to the traffic and communication network in modern cities. The performance of the bus directly affects the overall performance of the computer. The design of any system and the development of peripheral modules must obey certain bus specifications.

Brief introduction

Computer bus is the channel for transmitting information between computer modules. Bus technology occupies a very important position in the whole computer system, and its position in the microcomputer is equivalent to the traffic and communication network in the modern city. The performance of the bus directly affects the overall performance of the computer. The design of any system and the development of peripheral modules must obey certain bus specifications.

Bus technical performance index

The so-called bus technology is the communication standard between CPU and peripherals, which is a very specific communication protocol, including very complex technical specifications and parameters. As long as these protocols are followed in the design and manufacture, it can be well compatible with all kinds of peripherals and give full play to the performance of the computer system. The main performance indicators that describe bus technology are:

Bus width: the bit width of a transmission line, which consists of a data bus, an address bus and a control bus.

Bus frequency: the number of actions per unit time, that is, the bus working frequency, in MHz.

Bus transfer rate: the number of bytes transferred per unit time, measured in megabytes per second (MB/S).

Bus compatibility: whether low-level function cards, software and hardware can be used under advanced bus structures.

Bus load capacity: the number of expansion boards that can be connected.

The bus connects all kinds of components in the computer system, and the high-performance bus still needs good managers to play a better role, and the bus management system takes on this task. The task of the bus management system is to free the processor from the heavy bus management transactions, to contract out the work that does not need the participation of the processor, and to further improve the efficiency of the processor. In addition, the bus management system also needs to complete the management of DMA and other management, and realize the parallel operation of the processor and the Icano components.
