摘要：
Working on digital video encoders still is really crucial in digital multimedia communication systems. One of the most powerful video codec is H.264/AVC. The description of the Main Profile H.264 implementation on a DM648 digital signal processor is aimed in this paper. The encoder has been written in two phases, C-coded software on a desktop computer and the optimized one, which is appropriate for the DSP platform. Memory and cache tuning methods including algorithm parallelism were utilized in this process. Additional fast intra coding mode selection also exploited. Finally the encoder is able to encode QCIF sequences at the real-time speed.
