摘　　要：针对视频格式转换芯片的设计难点,提出了一种具有良好可扩展性和鲁棒性的自适应控制策略,进而论述了基于该控制策略的去隔行系统实现方案。根据去隔行算法特点,采用存储运动量的数据调度方案和流水线结构的处理单元,减轻了运算负担,提高了整体性能,在较低的功耗下完成了对视频信号的实时处理。To deal with difficulties in designing the video format conversion chip, the author brings forward a robust and well-extensible self-adaptive control strategy, and expatiates on the implementation scheme of its de-interlacing system based on the control strategy mentioned above. Due to the de-interlacing algorithm characteristics, a motion-value stored data transfer precept and a pipeline-based ALU are proposed to alleviate computational burden and improve performance. Thus, the system can fulfill real-time processing under relatively low power consumption.
