Problems solved by technology

The main reasons are as follows: First, FPGAs are generally used for the development of special-purpose products that are not widely used, but FPGAs have a disadvantage that their speed is not fast enough, and in the case of other indicators being the same, faster chips in the FPGA series are faster than chips. Slow chips are surprisingly expensive, and the speed of the 16-link bus of PCIe2. If the product is not mass-produced, its manufacturing cost is high
Second, because the speed of the 16-link bus of PCIe2.x or PCIe3.0 is too fast, developers must be very experienced, and they must also rely on advanced development tools and development platforms, which makes PCIe2.x or PCIe3.0 The development of the 16-link bus data output card has defects such as high development difficulty, long development cycle, and high development cost. It is very unsuitable for the situation where the product has a special purpose, the number of production is not large, the development cycle is short, and the product price should not be too high.

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 USB 3.0 transmission rate is 5Gbps, and the actual bandwidth is (5Gbps*8 / 10) / 8 = 500MB / s. [0005...
