Data scheduling policies for MPEG-1/2 video decoding is discussed in this paper according to software or hardware implementation case. Two 3-frames-grained scheduling policies are suggested to make good trade-off between processing demands and on-chip buffer demands in software decoding implementation.
在分析视频码流输入、解码处理和视频显示的时间参数后，提出以3帧组合为软件解码的调度粒度，以及基于启动期限和完成期限的两种解码调度策略，较好地均衡了处理器性能需求和数据缓存需求。
