摘　　要：根据对MPEG-2码流的实际处理,提出并实现了处理整帧数据中FIFO的控制,并着重介绍了其功能实现,同时给出VHDL程序以及仿真结果,这种方法很好地解决了普通FIFO写入和读出整帧数据的不完整的问题。In this paper, according to the processing of the frame of MPEG-2,the design of control for FIFO of processing complete frame is proposed and implemented. The functions of the control for FIFO are described emphatically. And also the program of VHDL for this design and the result of simulation are listed.This method can solve some problems when common FIFO writes and reads, such as the complete frames are half-baked etc.
