摘要
利用SAA7130视频采集芯片在VxWorks操作系统下实现视频采集系统。拥有PCI接口的一体化芯片SAA7130具有高度集成性。通过编写符合VxWorks I/O系统字符型设备驱动标准的SAA7130设备驱动,结合WindML图形库,实现了视频图像的采集与显示。实际运行效果表明该系统设计合理,运行稳定。
Implementation of video acquisition system based on SAA7130 video capture chip in VxWorks.With PCI interface integrated chip SAA7130 has a high degree of integration.By writing VxWorks I/0 system to drive the character device driver standard SAA7130 equipment meets,combined with WindML graphics library,and realizes data acquisition and display.The actual operation shows that the system is reasonable in design,stable operation.
