The characteristics of FIFO, double-port RAM and ping-pang cache structure were compared. The principle and features of ping-pang cache structure were discussed, and a real ping-pang cache structure was also given which consisted of high-speed, large capacity SRAM and FPGA. For a video processing system, this ping-pang cache structure is easy to interface with AD, DA and DSP.
