摘　　要：以EP2C35为核心处理器,提供了一种可行的实时图像采集系统。介绍了FP-GA在系统中的设计思想和工作内容,此设计集成了采集、存储、显示三大基本功能。针对视频解码芯片ADV7181B,实现了I2C总线配置、ITU656解码、VGA显示模块的设计。结果显示本设计具有速度高、成本低、易于集成等优点。A real -time video sampling system was presented by using an EP2C35 cyclone chip as the kernel processor. The idea and tasks of the FPGA design in the system which integrated three basic functions, namely sampling, saving and display were intr^xtuced briefly. The decode of ITU656 and the display of VGA modules were implemented on the video- decoding chip ADV7181B. The result shows that the system is highlighted for its high processing speed, low cost and easy integration.
