Performance improvement of the H.264/AVC deblocking filter using SIMD instructions

The H.264/AVC standard defines an in-loop de- instructions, available in current multimedia SIMD instruction blocking filter which is used in both the encoder and decoder. This sets. Lastly, we look at improvements achievable through work examines several methods for improving the performance adding new instruction extensions, specialized for the deof the H.264/AVC reference software implementation of the deblocking filter. Methods examined include general software blocking filter application optimization, parallelization through standard multimedia SIMD II BACKGROUND instructions, and augmenting standard SIMD instruction sets with new instructions. Using the above methods, we are are able A. Deblocking Filters achieve a large speedup of the deblocking filter computation. The block-based nature of many forms of video coding
