BUS, English called “bus”, that is, our Chinese “bus”, this is a very graphic metaphor. The bus route is certain and any of us can take the bus to any stop on the bus route. If we are an electronic signal, that’s why we call it “BUS” instead of “CAR.”

Of course, from the professional point of view, the bus is a kind of description of electronic signal transmission line structure form, is a collection of signal lines, is a common channel between subsystems to transmit information. Through the bus can make the whole system between the components of the information transmission, exchange, sharing and logic control and other functions. For example, in the computer system, it is the CPU, memory, input and output devices to transmit information public channel, each part of the host is connected through the host, the external device through the corresponding interface circuit and then connected to the bus.

With the development of modern network information, especially in terms of cost and space, bus transmission instead of point-to-point transmission is a hot topic in the current development. Its appearance will provide the most convenient and effective technical solutions for information transmission.

Basic components of the system bus:
Data bus, which transmits data information.
Address bus, which transmits address information.
Control bus, transfer control information (complete bus operation function).
Power cable: Provides power signals for the system.
First, the bus function

Data transmission function
The data transfer function is the basic function of the bus and is expressed in terms of the bus transfer rate, that is, the number of bytes transferred per second, in Mbps(megabytes per second).

Multi-device support
If multiple devices use a bus, the first problem is the ownership of the bus. Which master device applies to occupy the bus is determined by the bus arbitrator.

Middle break
Interrupts are the mechanism by which computers respond to urgent transactions. When a service agreement is made between the external device and the master device, the interrupt is the contact signal to realize the service agreement.

Error handling
Error handling includes detecting and handling errors such as parity check errors, system errors, and battery failures, and providing corresponding protection measures.
