摘要
提出了基于PCI Express总线传输的视频采集系统设计方案。采用ADV7188进行视频解码,能够采集多种格式模拟视频信号,而且提高视频信号的质量;采用Virtex-5系列的FPGA使系统设计灵活、集成度高且易升级。该系统采用PCI Express与PC进行通信,能够实现多路视频采集和海量数据传输,比高速USB总线的480 Mb/s的数据传输量提高了5倍。
Design and realization of video gathering system based on PCI Express bus transmission was briefly discussed in this paper. Using the ADV7188 of ANALOG DEVICES as the video decoder, the system could gather multiple format analog video and improve the quality of the video signal. With the use of FPGA of Virtex-5 series, it made the system designed more flexible, highly-integrated and easy to upgrade. The PCI Express bus and PC were used to communicate with each other in the system, which could realize muhi-channel video gathering and mass data transmission. The data transmission rate is 5 times higher than 480 Mb/s the rate of high-speed USB bus.
