H.264 is the most advanced video encoding standard,and its high complexity is the bottleneck in its applications.Based on the DSP of TI'S TMS320DM6446,a X264 encoder is designed.The local average difference of histogram is introduced to the amount determination of reference frames,and the little diamond search algorithm is used in the movement estimation process.Experiment results indicated that,quasi real time encoder of CIF video is achieved,while high image quality is preserved.
