基于FPGA的AVS反变换的设计与实现

Design and Implementation of the Inverse Transform of AVS Based on FPGA

根据AVS音视频编码标准中提出的反变换算法设计了一个基于FPGA的高效的反变换实现框架和方案。提出了一种新颖的一维反变换方法,不仅可以大大节约硬件资源,而且速度非常快。该反变换实现方案经过仿真验证,可以被用于1920×1080高清图像的AVS解码芯片中。

According to the algorithm of inverse transform in AVS audio video coding standard, this paper proposes a highly efficient hardware architecture for implementing the inverse transform function on FPGA. The new 1-D inverse transform implementing way introduced in this paper is extremely low-cost and high-speed. Simulation results show that the inverse transform method can provide satisfactory performances. As a result, this method can be used in 1 920×1 080 high definite image AVS decoding IC.
