High efficiency video coding standard H.265 was finalized in the recent progress of the high definition video technology. Though H.265 doubles the data compression ratio compared to H.264, it is dificult to fully bring out its compression performance due to the expense of increased computational complexity. Especially, in the motion estimation occupying most of the encode processing,a current practical encoder has to sacrifice coding efficiency because it cannot meet both speed and accuracy requirements.Therefore, SIMD data path formotion estimation has been designed to meet the two requirements so that it has highly efficient motion search capability in our laboratory. However, the motion estimation algorithm being suitable 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 worst load cycle of the reference image decreases by about 35%,and the amount of absolute difference operations for block matiching decreases by about 80% as compared to the motion estimation algorithm TZSearch used in the HEVC reference software. |
