Abstract :
The optimization of motion estimation in H.264/AVC encoder for video conference application is proposed. Firstly, an advanced diamond search algorithm is proposed. Then, for TMS320DM642´s special architecture, a hierarchical coded optimization is proposed based on the intrinsic functions. The optimized encoder is tested on TMS320DM642 platform, which confirms that the CIF format sequence can be encoded at 40fps or so.
