摘要 为解决最新一代视频压缩标准HEVC(High Efficiency Video Coding)中熵解码部分存在的语法元素串行依赖性问题,本文提出一种低时钟数冗余的CABAC(Context-BasedAdaptive Arithmetic Coding)硬件解码器实现方案.核心采用动态码表预处理方式和并行处理电路设计,提高了时钟利用效率,满足HEVC Level4.1 Main Tier的全部要求,可以以40 MHz的时钟完成1080HD@60fps的视频实时解码. To solve the serial dependency problem that came up with CABAC in the next generation of video coding standard called High Efficiency Video Coding(HEVC),this work proposed a low redundancy full system CABAC decoder solution. By adopting the dynamic codebook and parallel computing design, this work improved the clock efficiency and could satisfy the HEVC Level4.1 Main Tier and decode a 1080HD@60fps video with a clock of 40MHz.
