| Abstract: | TMS320DM642 is one high performance digital media processor recommended by TI Corp. Its two level cache structure could help to realize the high- complexity video coding algorithm efficiently. The algorithm, which takes the feather of the video coding and the two- level cache structure into account, would meet the requirement of the real- time application. In this paper, the DM642 cache structure is introduced first, and then accord- ing to the high complexity of video coding algorithm, a cache optimization strategy is proposed to realize the real- time video application system. |
