INTRA FRAME ENCODING USING PROGRAMMABLE GRAPHICS HARDWARE

摘要

GPU-based intra frame processing techniques are provided to selectively offload computation loading from a CPU to a GPU. By rearranging the 4x4 block encoding order, the process can benefit from a parallel processing mechanism available on the GPU. Block list size has an effect on speed and by using the optimal block list size for a selection, up to about two times speed improvement in intra frame processing can be achieved.
