Abstract :
The H.264/AVC standard defines an in-loop deblocking filter which is used in both the encoder and decoder. This work examines several methods for improving the performance of the H.264/AVC reference software implementation of the deblocking filter. Methods examined include general software optimization, parallelization through standard multimedia SIMD instructions, and augmenting standard SIMD instruction sets with new instructions. Using the above methods, we are able to achieve a large speedup of the deblocking filter computation
