摘要
研究了AVS音频编码标准中上下文位平面编码算法,分析了编码算法的特点。通过对上下文平面编码算法的优化,提出了一种适合ASIC实现的硬件结构,通过合理设计二级流水线,能近似达到每时钟1比特矢量的编码速率,在保证编码速度前提下大幅降低了硬件资源。
The CBC（Context-dependent Bitplane Coding） for AVS audio is studied. The characteristics of CBC are analyzed. Through optimizing CBC, a suitable architecture for ASIC implementation is proposed. With the lwo stage sound pipeline design, the speed of nearly one bit-vector per clock can be reached. Furthermore, the hardware resources are minimized on the base of the same encoding speed.
