【摘要】 以一个实际的视频编码系统为背景,提出了基于TMS320C6201DSP芯片的3种DMA方式数据传输方案,并对3种方案进行了比较分析与实验。实验结果表明,3种DMA方案不仅具有较高的数据传输效率,而且对各类视频场景具有通用性。更多还原

【Abstract】 Considering cost,size and performance,most real-time video encoder systems are designed for working on hard-ware.While in hardware implementations,how to make the best of enormous video data during encoding is one of the most important issues when the system is being designed.In this paper,we propose three methods of DMA data transmission in video encoder based on C6201DSP of Ti Inc.for a real video encoder system.Further more,we experiment on these three methods.Experiment results show that the methods not only have high performance but also adapt to various video scenes.[更多还原
