Abstract

The invention discloses a universal data transmission system, comprising a computer host and at least one data transmission device, wherein the computer host is configured with at least one display interface. The computer host is connected with the data transmission device by the display interface. The computer host is mainly used for transmitting high-speed transmitted data to the data transmission device through the display interface according to transmission rate requirements of the data transmission device. The data transmission device receives the data transmitted by the computer host at high speed, and converts the data to be data form required by external equipment which is connected with the data transmission device and outputs the data. In the technical scheme of the invention, a graphics card or an accelerated processing unit having graphics card functions is used as a switching device of data transmission by use of the mature graphics technology, so that the display interface can transmit data which satisfies the transmission rate requirement to the data transmission device. Moreover, According to the technical scheme, the development difficulty of the data transmission system is reduced, the development period is shortened, and the development cost is reduced.

Description

technical field

[0001] The invention relates to a general data transmission system. Background technique

[0002] The data output channel is an essential part for data transmission of computer control systems and various intelligent instruments, signal generators, audio and video players, etc. With the development of science and technology, the requirements for data transmission rates are increasing day by day. There are more and more needs for high-speed data output cards for various applications, and they are becoming more and more urgent.

[0003] Computer control systems and many high-end intelligent instruments, signal generators, audio and video players, etc. are all based on computers, and the common fast buses for computers mainly include USB, PCI, and PCIe. The transmission bandwidths of these three buses are respectively for:

[0004] 1. The theoretical bandwidth of USB3.0 transmission rate is 5Gbps, and the actual bandwidth is (5Gbps*8 / 10) / 8=500MB / s.

[0005] 2...
