Abstract

AVS2 is a kind of advanced video coding standard developed by China, which achieves the same compression efficiency as the international standard HEVC/H.265. In intra coding, there are 33 intra prediction modes, and the optimal intra prediction mode is obtained by calculating Rate Distortion (RD) cost of each mode. Rough Mode Decision (RMD) is an essential part of intra coding in AVS2, which reduces intra coding complexity significantly. However, in traditional RMD algorithm, the Sum of Absolute Transform Difference (SATD) is calculated of all 33 prediction modes, which greatly increase computing resources and time complexity. In this paper, both fast mode decision algorithm and its efficient architecture based on texture information and SATD cost is proposed. Verified by the Xilinx Vivado HLS, the experiment results show that the algorithm and architecture proposed in this paper is able to process video of 1920x1080@60 fps under the 300MHz clock frequency with a 2.0% BD-rate increase in average.
