| Abstract: | An efficient in-loop de-blocking filter is proposed,which supports H.264 BP/MP/HP and AVS video decoding.In order to use the same filter architecture to process all of the H.264 and AVS MBs,the edges are redefined in a MB needed to filter.By using a novel hybrid filter order and MB division strategy,it can increase the intermediate data reuse and decreases the memory resource on chip.With pipeline and parallel process strategy,it can increase the data throughput.Adopting TSMC 65 nm CMOS technology,the propo... |
