AVS解码器中帧内预测模块的设计与实现

Design and implementation of intraframe prediction module for AVS decoder

阐述了AVS视频解码器的总体框架,详细分析了帧内预测的原理与算法,提出了一种可行的帧内预测解码器的硬件设计,给出了每一模块的功能和结构的详细介绍,并建立了一种高效的存储机制。通过FPGA平台的验证,表明本设计完全满足AVS标清视频的实时解码要求。

After the overview framework of AVS video decoder, principle and arithmetic of intraframe prediction are introduced, we propose a rational hardware design of intraframe prediction decoder, introduce the function and structure of all the module, and set up an efficient storage mechanism. The results of FPGA testing show that this design completely satisfy the real-time decoding demand of AVS standard definition video.
