【Abstract】 In this paper,multi-dimensional matrix video compression algorithm is discussed and implemented.Considering the characteristic of the algorithm,research of real-time on the multi-dimensional matrix video compression algorithm is implemented on the parallel DSP system whose processing core is TMS320C6201.There are both two DSPs to accomplish the encoding and decoding with pipeline technique in the encoder and decoder.Reconstruction images and data of the real-time simulation experiments are given and compared with MPEG.Simulation results demonstrate that this algorithm and architecture which can compress video image in real-time and effectively would have a very good spectacle in the area of real-time video coding.更多还原
