【Abstract】 For the real time compression and transmission of motion images, an overall solution is carried out which combines multiplication/addition, parameter conversion, matrix transposition and data loading and clipping to construct a 64 bit parallel two dimensional DCT core. As a result, the operations for compressing and decompressing of motion images is simplified, the CPU time for two dimensional DCT and motion estimation dropping about a dozen times, and real time compressing and decompressing can be achieved completely.更多还原
