摘要
本文介绍了基于帧存储器AL422缓冲的视频处理器,采用硬件描述语言VHDL控制帧存储器作乒乓切换操作的控制时序,输出数据重构成完整帧视频,应用于视频拼接。
The article made a introduction about the video processor which based on the frame memory AIA22, which use the hardware description language VHDL to control the frame memory to handoff the timing control in the manner of ping-pong, then output the rebuilt a whole video, which used to video mosaic.
