摘要
Bt878A视频采集卡和Intel X86微机性能稳定、价格低廉。提出了一套利用Bt878A芯片的视频采集卡在Intel X86平台和嵌入式操作系统VxWorks上实现电视图像取差测偏的方案。通过开放高速缓冲,使PCI总线下,对于90×60像素的波门,处理时间由50 ms缩短到 5 ms。
The Bt878A video collection card and the intel X86 PC have steady capability, broad quarry and vile price. A blue print of using Bt878A video collection card on intel X86 PC and VxWorks operating system to get a warp in a video image is presented. The video processing rate under PCI BOS meet the demands by opening the high speed catch.
