英文摘要	In this paper, we propose a hardware architecture of an adaptive multi-resolution motion estimation algorithm (AMMEA) for high definition video encoder to reduce hardware cost. The texture-based search strategies are based on temporal stationarity and spatial homogeneity with Sobel edge operator. The proposed algorithm makes motion estimation more concise. We also propose Sobel edge operator hardware architecture. The four-pixel SAD unit which is the basic processing element (PE) in our proposed architecture is used for SAD calculation and Sobel edge operator computation. The hardware architecture achieves very high data utilization and data throughout. Using our proposed AMMEA with regular data flow, simulation results show that the proposed architecture can significantly reduce the hardware cost with a negligible PSNR loss of 0.03dB compared with the full-search. The design is implemented with SMIC 0.18 mu m CMOS technology and costs 950K gates count, and it supports the real-time encoding of 1080P@30fps with two reference frames under a clock frequency of 150MHz.; CPCI-S(ISTP); gqxiang@jdl.ac.cn; hzjia@jdl.ac.cn; liuzimin@jdl.ac.cn; yuanli@jdl.ac.cn; xdxie@jdl.ac.cn; 2194-2197
