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.
