    为了提高数据传输带宽和可靠性,设计了基于PCIE总线的视频采集系统.在VxWorks操作系统下,驱动程序使用MSI中断方式和DMA传输机制,把FPGA压缩编码后的H.264码流通过PCIE总线传输至系统内存.测试表明驱动程序能满足视频采集系统传输要求.

    In order to improve data transmission bandwidth and reliability, a set of video capture system based on the PCIE interface is designed. In VxWorks operation system, the driver uses MSI interrupt and DMA transfer mode, and it transfers H.264 data compressed by FPGA to system SDRAM. Tests prove that the driver can satisfy the transfer request of the video capture system.
