Shu-Sian Yang, Sung-Wen Wang, Ja‐Ling Wu · 2007
In this paper, we propose a parallel algorithm for H.264/AVC deblocking filter which is scalable to the number of processors. Unlike the conventional approach, which is limited by the independent data units, the designed algorithm allows issuing dependent data units concurrently to decrease the penalty from synchronization of data units. For the general-purpose dual-core processors, experimental results show that our method speeds up 1.72 and 1.39 times as compared with optimized sequential method and the well-known wavefront parallelizing method, respectively.
