| Abstract: | This paper mainly introduces the advantage of parallel computation based on GPU platform, and gives an introduction to the developing framework and programming environment based on GPU platform. Develop codes of DCT algorithm in CUDA environment to realize the algorithm transplant of DCT from DCT to CPU platform. By contrasting two calculation times on the different platforms, the advantage of the GPU calculating platform will be indicated. |
