Abstract
The concurrent operation of SAD value computing can be actualized by use of the SIMD technology, We give the image organization optimization algorithm of improvement from the image of Single Instruction Multiple Data parallel operation，Such as the idea of oriented object to lead into Parallel operation process that calculated SAD value．through the test result of code device moving forecast for Multi Media extension optimization velocity testing，we know that in current most complex video coding H.264／AVC，the implement of this algorithm can raise the coding speed of encoder obviously，and offer guarantee to realize the video communication of real time in narrow bandwidth.
