A memory-efficient deblocking filter for H.264/AVC video coding

Abstract

A memory-efficient architecture design for de-blocking filter in H.264/AVC is presented. We use the novel data arrangement of Column-of-Pixel to facilitate the memory access and reuse the pixel value. Further, we propose a hybrid filter scheduling to improve the system throughput. As compared with some existing approaches of realizing de-blocking filter [1] [2], the proposed design saves about one-half of processing cycles. With novel data arrangement and hybrid filter scheduling, an efficient architecture design is implemented. Further, it is evaluated on H.264 system and easily achieved real-time decoding with 1080 HD (1920x1088@30fps) when working frequency is 100MHz.
