摘要

由于高清晰度(HD)或更大分辨率视频对H.264/AVC解码的性能要求越来越高，需要新的方法来实现实时处理。随着多核体系结构的发展，在多核处理器环境下采用并行译码是一种高效的方法。根据H.264/AVC标准的特点，分析了译码算法的并行性，设计了一种混合分解并行化方法，并在TILE64多核处理器上实现了并行译码。实验结果表明，解码器的性能得到了很大的提高。

Research of parallel decoding algrithm in H.264 on TILE64

Due to the increasing performance requirements of decoding H.264/AVC in High Definition (HD) or larger resolution videos, new approaches are necessary to realize real-time processing. With the development of multi-core architecture, it's efficient to adopt parallel decoding in the multi-core processor environment. According to the characteristics of H.264/AVC standard, this paper analyses the parallelism of decoding algorithm, designs a parallelization approach of Hybrid decomposition, and implements parallel decoding based on the TILE64 multi-core processor. The experiment result proves that the performance of decoder can be improved greatly.
