作为H.264/AVC的后续视频压缩标准，高效视频编解码器(HEVC)将在视频编码领域发挥重要作用。在去块滤波部分，HEVC继承了H.264/AVC的基本特性，并赋予了一些新的特性。在此基础上，本文提出了一种既支持HEVC标准又支持H.264/AVC标准的双模去块滤波器结构。对于HEVC标准，提出的基于对称统一交叉单元(SUCU)的滤波方案大大降低了设计复杂度。因此，处理16×16块需要24个时钟周期。对于H.264/AVC标准，16×16宏块(MB)需要48个时钟周期。综合结果表明，在中芯国际65 nm库中，该结构在200 MHz频率下占用了41.6k等效门计数，能够满足60fps的超高清吞吐量要求。采用滤波器重用方案，两种标准的通用设计比专用设计在滤波部分节省了30%的门数。此外，当不需要填充边缘时，跳过模式可以将总功耗降低57.2%
SUMMARY As the successive video compression standard of H.264/AVC, High E fficiency Video Codec (HEVC) will play an important role in video coding area. In the deblocking filter part, HEVC inherits the basic property of H.264/AVC and gives some new features. Based on this variation, this paper introduces a novel dual-mode deblocking filter architecture which could support both of the HEVC and H.264/AVC standards. For HEVC standard, the proposed symmetric unified-cross unit (SUCU) based filtering scheme greatly reduces the design complexity. As a result, processing a 16×16 block needs 24 clock cycles. For H.264/AVC standard, it takes 48 clock cycles for a 16 × 16 macro-block (MB). In synthesis result, the proposed architecture occupies 41.6k equivalent gate count at frequency of 200 MHz in SMIC 65 nm library, which could satisfy the throughput requirement of super hi-vision (SHV) on 60 fps. With filter reusing scheme, the universal design for the two standards saves 30% gate counts than the dedicated ones in filter part. In addition, the total power consumption could be reduced by 57.2% with skipping mode when the edges need not be fil
