摘　　要：描述了一种可以支持实时数据流处理的帧同步方法。该方法用SDRAM做帧存储器,存放一帧视频数据,用FPGA实现数字视频解串、串化、帧同步逻辑控制以及SDRAM控制器等功能,用同步器连接异步模块的方法解决异步时钟域信号传输问题。该设计方法可完成标清数字视频的帧同步功能。A frame synchronized method is introduced which can deal with the data steam timely. A serious of submethods are used to consist the method which include using the SDRAM as the frame memorizer to memory a frame video data, using the FPGA to realise digital video deserialization, serialization, frame synchronization logic control and SDRAM controller. The problem is also solved that asynchronous clock domains signal transmission by using synachronous controller connects with asynachronous module. Though the download debugger, this method can completely realise SD digital video synchronization function.
