The new video coding standard H.264 has used the method of intra prediction. Compared with the video standards before, H.264 intra prediction enhances the efficiency of video coding drastically. Although the new method reduced the bit rate, it also increases the complexity of the encoder. So it is necessary to optimize the algorithm in H.264 for the practical application. In this paper, at first we introduce the process of intra coding in detail, then present the fast implement method using SIMD(single instruction multiple data). Experimental results show that the speed of intra coding is obviously improved using proposed technique.
