An area-efficient and high-throughput de-blocking filter for multi-standard video applications

In this paper, we propose an area-efficient design approach to cover both in-loop and post-loop filtering processes for multiple video coding standards. In addition, we propose a hybrid filter scheduling to improve system throughput. Compared with available designs [Yu-Wen Huang et al, 2003][M. Sima...

Description
Summary:In this paper, we propose an area-efficient design approach to cover both in-loop and post-loop filtering processes for multiple video coding standards. In addition, we propose a hybrid filter scheduling to improve system throughput. Compared with available designs [Yu-Wen Huang et al, 2003][M. Sima et al, 2004], the proposed approach saves about one-half of processing cycles, and hence reduces power dissipation. Compared to the original loop-filter, the proposed loop/post filter only incurs 20.7% of extra cost. Simulation results show that our proposal can easily achieve real-time decoding for 1080HD when the working frequency is 100 MHz.
