摘　　要：提出一种适用于AVS视频解码器逆扫描、反量化和反变换的硬件结构优化设计方案,该设计把逆扫描、反量化和反变换过程结合在一起进行设计,以宏块为单位进行操作且在块与块之间采用了流水线技术,并通过采用乒乓技术和寄存器复用技术达到速度和面积的平衡和优化。本设计在Quartus II 8.0上进行了仿真,仿真结果与C中结果进行了比对,通过在基于Nios II的AVS视频解码系统测试平台上进行测试,证明了该模块功能的正确性。Optimized hardware architecture of reverse scan, inverse quantization and inverse transform for AVS decoder is pro- posed. The design is on maerobloek level and bloek-pipelining is used. To achieve balance and optimization of speed and area, the technology of ping-pang and registers reuse are used. The design is verified in Quartus Ⅱ 8.0 and the simuIation results are compared with the results of C. By being tested on the Nios Ⅱ-based testhench of AVS video decoder, the module is proved to work well.
