As the successive video compression standard of H.264/AVC, High Efficiency Video Codec (HEVC) will play an important role in coding area. In deblocking filter part, HEVC inherits basic property H.264/AVC and gives some new features. Based on this variation, paper introduces a novel dual-mode architecture which could support both standards. For standard, proposed symmetric unified-cross unit (SUCU) based filtering scheme greatly reduces design complexity. result, processing 16×16 block needs 24 clock cycles. it takes 48 cycles for macro-block (MB). synthesis occupies 41.6k equivalent gate count at frequency 200MHz SMIC 65nm library, satisfy throughput requirement super hi-vision (SHV) 60fps. With reusing scheme, universal two standards saves 30% counts than dedicated ones part. addition, total power consumption be reduced by 57.2% with skipping mode when edges need not filtered.
