Optimization and Implementation of H.264 Encoder on DSP Platform

Compared with MPEG-4 and other previous standards, H.264 standard has achieved great breakthrough in coding performance. In this paper, the optimization and implementation of H.264 baseline profile encoder on the TMS320DM642 has been presented. Based on the architectural features of TMS320DM642 and the computational complexity analysis of H.264 encoder, the H.264 encoder has been optimized from three aspects: algorithms, data transfer and memory/Cache use. The experimental results demonstrate that, for the video sequences with CIF format, the optimized H.264 encoder can achieve the encoding speed of more than 24 frames per second, which can meet the real-time requirements of the applications.
