Abstract
As the widely application of digital multi-media technology, H.264 has become one of the most popular video standards for its better performance. This paper proposes optimization methods of the x264 decoder which is an implementation algorithm of H264 based on DaVinci Technology, especially including taking advantage of the DMA resource and cache optimization strategy in purpose for memory access. We choose TMS320DM6446 as our platform which is a DaVinci-based multi-core processor. The results show that the optimized x264 decoder can process in real-time without any loss of performance.
