摘　　要：为了满足视频解码器设计的需要,对AVS-P2视频解码器进行了复杂度分析[1]。首先根据AVS解码器的内存使用情况进行空间复杂度分析;其次通过计算解码器主要子功能模块的基本操作数从理论上估算解码器的时间复杂度;最后,对AVS解码器在一系列测试序列上的实际计算复杂度进行了统计分析。证明了AVS-P2视频解码器复杂度比H.264视频解码器复杂度更低,更适合于在各种软硬件平台上高效的实现。实验结果进一步验证了对AVS-P2解码器复杂度的分析。The complexity analysis of AVS-P2 video decoder is performed for meeting the requirement of video decoder architecture design.First,the memory requirement of AVS-P2 decoder is taken as the basis to analyze spatial complexity;second,the number of basic operations of principal sub-module of AVS-P2 decoder is calculated for theoretically estimating the time complexity of the decoder;Last,the statistical analysis is performed on actual computational complexity of a series of testing sequences,and this proves that the complexity of AVS-P2 decoder is lower than that of H.264 video decoder,so the former is more suitable to be efficiently implemented in a variety of software and hardware environments.Experimental result further validates our analysis in the paper on AVS-P2 decoder complexity too.
