The latest H.264/AVC standard can provide us superior coding performance. However, the new technique also brings about complexity problem, especially in motion estimation (ME) part. In hardware, the pipeline stage division of H.264 based ME engine degrades many software oriented complexity reduction schemes. In our paper, we propose one VLSI friendly fast ME algorithm. Firstly, pixel difference based...
The computational complexity and hardware design of block-matching criteria were discussed, and a novel MPDC algorithm and its VLSI structure for H.264 were presented, in which a QP adaptive MPDC threshold was derived from the basics of H.264 4??4 integer transform and 52-level scalar quantization and the calculation process was adjusted for hardware optimization. When QP is greater than 18, the proposed...
