Fully parallel fractional motion estimation for H.264/AVC encoder
Fractional motion estimation always takes much processing time because of variety of motion vectors and two-step sequential half-quarter pel. In this paper, we propose the architecture of fractional engine in fully parallel manner. Instead of sequential processing two-step of half-quarter refinement, integer-half-quarter pel is processed in parallel manner in order to double the speed as well as the throughput. Using Chartard 0.18 μm CMOS 1P5M technology, the proposed architecture is implemented with 412k logic gates and achieves the throughput of 255 kMBs/s supporting HDTV1080p 30 fps when operating at the frequency of 220MHz.
