The Optimization of H.264 Encoder Based On TI TMS320DM642
H.264 standard achieves higher compression ratio than previous standards with additional complexity as a price to pay in implementation. To apply H.264 in mobile multimedia terminal, implementation and optimization on platform must be studied. This paper introduces some optimization ideas and describes optimization techniques to realize real-time encoder on TMS320DM642 or equivalent chip. Some corresponding experiments have been performed on the un-optimized encoder. The optimized encoder and the results are presented here. The encoding speed is improved almost ten times after the optimization, and can realize the real-time encoding on QCIF sequences.
