摘要：
Nowadays, mobile devices are capable of displaying video up to HD resolution. In this paper, we propose two acceleration strategies for Audio Video coding Standard (AVS) software decoder on multi-core ARM NEON platform. Firstly, data level parallelism is utilized to effectively use the SIMD capability of NEON and key modules are redesigned to make them SIMD friendly. Secondly, a macroblock level wavefront parallelism is designed based on the decoding dependencies among macroblocks to utilize the processing capability of multiple cores. Experiment results show that AVS (IEEE 1857) HD video stream can be decoded in real-time by applying the proposed two acceleration strategies.
