Vectorized deblocking filter for HD H.264 decoding on Cell/B.E.

For high definition (HD) H.264 decoding, deblocking filter is one of the most time-consuming modules. This paper proposes several vectorization approaches to speed up it on a single synergistic processor element (SPE) of IBM Cell Broadband Engine (Cell/B.E.) processor, by which great performance improvements are achieved. The average deblocking speed is 42… (More)
