- Abstract
- We present an enhanced fast motion estimation algorithm for Full HD (1080p) High Profile H.264/AVC. Most of processing cycles are occupied with motion estimation and use external memory access to fetch samples, which degrades the performance of the encoder. A novel approach to fast motion estimation with that uses shared multi-bank memory can solve these problems. The proposed enhanced hierarchical search algorithm is suitable for fast motion vector (MV) searches for highquality resolution images. The proposed algorithm not only achieves an 87.5% reduction of computational complexity compared with the full search algorithm in the JM reference software, but also sustains the video quality without any conspicuous PSNR loss.
