摘要 提出了一种应用于H.264/AVC的快速低功耗CAVLC解码器设计方法。对较复杂的几个模块进行了算法和结构上的优化,减少了占用的硬件资源,降低了实现复杂性。仿真结果表明:采用该方法设计的解码器可以正确解码每个变换块中的变换系数,且能在一个时钟周期解出一个句法,完全可以满足H.264视频实时解码的要求。 The paper presents a method of high-efficient and low-cost CAVLC decoder to H.264/AVC standard. Several complex modules are optimized in arithmetic and architecture. The hardware resources are cot and the complexity of realizing the design is reduced through these methods. The result shows that the decoder can decode the coded stream of transform coefficients in each block. Moreover, it can decode one syntax element in one clock cycle, which means that it can satisfy the demand of real time decode in H.264/AVC standard.
