| Abstract: | Motion compensation decoding process is one of the most complicated parts in H.264 decoder. In this paper, several im- provement measures are presented based on Blackfin533 hardware platform, such as C code optimization, DMA technology and the assemble optimization strategy. Experimental resuhs show that the proposed optimization strategy can greatly improve the efficiency of real time H.264 decoder. |
