| Abstract: | According to the feature of coarse grain reconfigurable processor, this paper introduces an approach that implements 2D-DCT on coarse grain reconfigurable processor. This approach develops the parallelism of algorithm effectively in the condition of limited hardware resources. As a result, it can get better resource utility and faster speed in comparison with microprocessor and meet the demand of real time picture coding and decoding. |
