Abstract: Software implementations of MPEG decompression provide flexibility at low cost but suffer performance problems, including poor cache behavior. For MPEG video, decompressing the video in the implied order does not take advantage of coherence generated by dependent macroblocks and, therefore, undermines the effectiveness of processor caching. In this paper, we investigate the caching performance gain which is available to algorithms that use different traversal algorithms to decompress these MPEG ... (Update)
