基于FPGA的AVS视频解码帧内预测的设计和实现

Design and Implementation of Intra Prediction in AVS Video Decoding Based on FPGA

根据AVS标准中帧内预测的算法,运用流水线设计方法,并合理安排缓冲存储器空间,利用FPGA实现了帧内预测系统;然后将该设计的ModelSim仿真结果与参考软件的解码输出进行了比较,结果表明本设计能够较好地完成帧内解码算法,方便地嵌入到整体AVS解码系统中。

According to the intra prediction algorithm in AVS standard, the intra prediction system with pipeline design method and reasonable arrangements of cache RAM based on FPGA is designed and implemented. Then comparing ModelSim simulation results with the reference software decoder output, it shows that this design is able to complete the frame decoding algorithm, and can easily be embedded into the overall AVS decoding system.
