Abstract :
This work presents a fast multi-resolution block-matching algorithm (FMRME) for MPEG-2 video encoding, which provides an outstanding PSNR performance close to the full search algorithm. We also propose the hardware architecture of the FMRME for real-time MPEG-2 video encoding with a large search range of [-192.0, +191.5]. Due to efficient data reuse and parallel processing, the utilization percentage of PE is also very high. We implemented this architecture with about 100 K gates and 5 K bytes SPSRAM.
