Abstract(in English) | High efficiency video coding standard H.265 doubles the data compression ratio compared to H.264, however it is difficult to fully bring out its compression performance due to the expense of increased computational complexity, especially, in the motion estimation occupying most of the encoding time. A current practical encoder has to sacrifice coding efficiency because it cannot meet both the speed and accuracy requirements. Therefore, we had designed SIMD Data path with highly efficient local search function for motion estimation in our laboratory. However, the motion estimation algorithm for the SIMD Data path has not developed yet. This paper proposed highly efficient motion estimation algorithm frequently using SIMD instructions for small search range. As a result, the number of loading operations decreases by about 74% and the amount of absolute difference operations for block matching decreases by about 81% as compared to the motion estimation algorithm TZSearch used in the HEVC reference software. |
