| Abstract: | This paper introduces the features of high - speed DSP- MAPCA, based on which most emphasis is on the optimization of the H. 261 video decoder, including reasonable adjustments of the program framework, the optimizations of the main program module IDCT and the I- quant. The decoding time after the optimization only takes one - third of the original. |
