%X The SIMD(Single-Instruction Multiple-Data) instruction system was introduced,and further Integer DCT(Discrete Cosine Transform),quant,interpolation and motion estimation of H.264 were optimized with the SIMD technology.The experiment indicates that the encoding speed of program after optimization reaches about 30fps and the speed has been improved by 6~8 times.
