A hardware sharing architecture of deblocking filter for VP8 and H.264/AVC video coding

In this paper, a hardware sharing architecture to perform the multi-standard deblocking filter that support VP8 and H.264/AVC is proposed. First, a reorganization of deblocking filter is used to derive a common architecture suitable for H.264 and VP8. The proposed design is then reused for the whole filtering. Finally, to further reduce the computational complexity, highly sharing architecture is also presented. Moreover, the adopted hardware sharing architecture overall saves 36.7% of shifters, 64.5% of adders and 100% of multipliers. The overall PSNR drops less than 1.47% on the VP8 decoder for low complexity applications.
