| 摘 要： | 为提高AVS和H．264反量化算法硬件资源的利用率，设计了一种能够兼容2种解码标准的反量化模块．在分析了AVS和H．264反量化算法的基础上，给出了两者之间的异同点．并根据反量化算法的特点，采用基于算法和硬件模块的复用技术，提出了一种资源复用的硬件架构，不但实现了同块中4个像素点的并行运算，而且实现了H．264中直流块和交流块的并行处理．仿真结果表明：该模块能满足高清数字视频的实时处理应用．

| Abstract: | In order to improve the efficiency of hardware resources of AVS and H.264 inverse quantization algorithm,a new inverse quantization module is designed,which is compatible with two video decoder standards.Analysis of AVS and H.264 inverse quantization algorithm is first conducted by presenting the similarities and differences between these two standards.Based on multiplying technology in the algorithm and hardware module,a hardware architecture scheme for resources multiplication is proposed.The presented de... |
