摘要
视频监视系统在数据传输的实时性、高速性和中断响应上有着较高的要求。为此设计了一种在x86平台下利用实时操作系统VxWorks,采用PCI总线的视频数据采集显示系统并实现了视频监视功能。介绍了采用BT878A芯片的PCI采集卡的驱动设计,RISC指令执行流程及视频显示方法。
Due to the high demand to real time, high speed and interrupting response,it is necessary to use a high performance realtime operating system to establish the video data collection system.With the real time operating system VxWorks,a video surveillance system using PCI bus,which is based on x86 platform,was designed.The article introduced the design of video capture card driver, gave the sequence of the RISC instructions and the method of video display.
