Implementation and Optimization of H.264/AVC Encoder on Blackfin (ADSP-BF537) Processor
Yan Shi-lei, Jian-wei Sun · 2006
Real-time video images communication needs efficient implementation and optimization about the video compression algorithms on power-efficient platforms. To meet such needs several compression methodologies and techniques have been proposed and standardized. This paper presents the implementation details of H.264/AVC (the latest standard for video compression) encoder on ADSP-BF537 processor based Analog Devices BF537-STAMP board, and gives several optimization techniques which have been concurrently employed in this work to improve the performance of the encoder. In this paper, the improvement in performance has been evaluated for each optimization step and the results of the optimization demonstrate the potential of the low- power Micro-Signal Architecture of Blackfin processor as a good choice for next generation embedded multimedia applications.
