SIMD-based datapath with efficient operation structure for motion estimation

Even high-performance general purpose processors are not sufficient for speedy motion estimation (ME), though they support some SIMD instructions for ME. In this paper, we propose a SIMD-based general-purpose-oriented datapath with efficient operation structure for ME. The several additional components have been added to a comven-tional datapath base for ME acceleration. The results of its logic design and chip layout design showed the proposed datapath accelerates motion estimation speed by 3.99-5.06 times on average in the diamond, SUC and non-dense patterns compared to previous method with only 2.6% hardware area increase.
