摘要
为了解决大容量实时视频信号存储器存储延时,以及速率慢、总线利用率低的问题,提出一种基于视频帧信号,切换SDRAM和切换Bank完成视频信号快速、连续存储控制器的设计思路,解决了存储器总线效率低,视频帧信号不能完整顺序保存的问题。为后续视频处理器提供了高质量、高速率的视频码流,向实时视频监控DVR的设计奠定了基础。
To solve the problems of the low efficiency and slow accumulation storage a new method is presented to switch Bank and SDRAM way to get the video frame stored up fast and consecutively. This method increases the bus efficiency, prevents the scattered frame storage and establishes the design foundation of the remote monitor system.
