摘　　要：介绍了视频标准H.264中的4×4整数变换原理及一种一维整数变换的快速算法,在此基础上利用Kronecker乘积推导出一种适合于TMS320C64系列的二维整数变换的并行算法,结合TMS320C64系列的VILW和SIMD特点进行了相应的优化,提高了算法的并行度。The principle of 4×4 Integer Transform （IT） of H.264 and a fast 1-D algorithm are introduced. And then, a parallel algorithm of 2-D IT which suits for TMS320C64 series is proposed by using Kronecker product. The algorithm is optimized based on the features of VILW and SIMD of TMS320C64 series, and the parallelism is improved.
