摘　　要：针对自制的ADSP-BF561解码器平台的特点,提出了样本插值的快速算法,提高了运动补偿部分执行的效率。结合汇编指令级优化及存储优化等策略和方法对AVS解码模块进行全局优化,试验结果表明D1画质的视频基本满足了实时解码的要求。In allusion to the features of self-manufacturing ADSP-BF561 decoding platform, the fasting algorithm of sample differences is proposed, and execution efficiency of motion compensation part is improved. Meanwhile, several strategies and methods are used to completely optimize the AVS decoding module, including the instruction-level optimization of assemble and storage optimization. The experimental results show that the video with D1 quality can basically satisfy the real-time decoding requirements.
