The strategy of Ping-Pongbuffer allows data transfer and code to perform simultaneously.
该算法采用乒乓缓存策略,使得数据的传输和编码能够同时进行。

In the video CODEC module, the design based on ADV7183 was proposed. To improve the data access efficiency, a data structure called ping-pongbuffer was presented for the input video data.
The system makes use of two group of outer SRAM to buffer the frame data, and USES ping-pong operation of the SRAM to achieve the video display in series.
