| 摘 要： | 针对VC-1标准下的WMV视频解码，提出了一种基于CEVA平台下的优化方案。该方案对运动补偿、去方块滤波、反量化、反变换的算法结构进行优化后，再利用CEVA的SIMD（单指令多数据处理）和VLIW（超长指令字）技术实现DSP平台上的优化。实验仿真表明：经过优化处理后，各个模块解码时间对比之前有了大幅度降低．解码速度最高...

| Abstract: | An optimization for decoding WMV（Windows Media Video） based on CEV_A platform for video code one standard is proposed in this paper. With the SIMD（Single Instruction Multiple Data） and VLIW（Very Long Instruction Word） technology, optimization could be implemented after the data-processing method in Motion Compensation,De-blocking Filter,De- quantization,Inverse Transform adjusted. The experiment shows that the decoding rate could reach 30 fp/s after optimization and the propose design could perform real-time decoding for standard definition and high definition video decoder. |
