Abstract :
This paper describes an innovative, pipelined, cache-based architecture for a motion estimation coprocessor. The coprocessor is based on a predictive/recursive algorithm whose computational complexity is low and not dependent on the search window. The synergies between the architecture and algorithm´s features allow a high quality, low-area, low-bandwidth, search window implementation for standard resolution (PAL/NTSC), low resolution (CIF/QCIF) or high resolution (ATSC) sequences
