[Abstract]:With the development of the distributed test system and the improvement of the performance of the data acquisition equipment, the high speed and large capacity data generated in the test need fast, reliable and long distance real-time data transmission. A high-speed real-time data transmission system based on PCI bus technology and LVDS interface technology is designed in this paper. The project is a sub-project of a certain project. Based on the analysis of the taskbook and the technical index, the overall scheme of the system is designed, and the PCI bus technology is applied. Ping-pong buffer technology LVDS signal technology and DMA data transmission technology. In the hardware design part: mainly describes the system function module, uses the high performance FPGA to realize the LVDS interface control, the data reorganization, the clock conversion, Two SDRAM memory chips are used to realize the transmission control of the Ping-Pong buffer SDRAM interface control module, and the PCI9054 chip is selected as the PCI bus controller. In the part of software design: combined with the process of data reading, the driver of PCI device is compiled by DriverStudio driver software, and the development process of driver is introduced. It realizes the requirements of hardware interrupt request response, data transmission and so on, and completes the corresponding application interface development by using VC6.0 environment, realizes the corresponding functions such as state reading, control command generation, data analysis and processing, and so on. At the end of the paper, the experimental process and the data analysis results of the PCI transmission system are given. The test results show that the PCI transmission system has basically fulfilled the design requirements. The research of high-speed real-time data transmission system based on PCI bus technology has attracted more and more attention.
