Technology And Research Of High-Speed Data Transfer Base On PCI Express

With the extensive development of computer science and video technology, the digital image acquisition has been widely used in the fields of electronic communications and information processing. The video capture card, as the front-end equipment in computer video applications, assumes the responsibility of converting the analog video signals into digital video signal. Therefore, designing a video signal acquisition circuit boasting of flexible functions, user-friendliness and which is easy to be embedded the into the overall system has important significance in actual practice.This paper first introduces the latest and future development of PCI and then puts forward the goal of this design:Based on Virtex-5 XC5VSX50T FF1136-1C chip and directly using the primitive description of Xilinx FPGA's underlying hardware, so as to put FPGA's performance into full play. By using the Xilinx's IP core generator tool CORE Generator, we enable the FPGA chip to generate PCI-E bus interface by means of FPGA programming.Finally, the paper shows the verification results of the FPGA program and integrated debugging result of the overall system, making a summary of the system development process and providing forecast of the future development in acquisition cards.
