ABSTRACT:
A motion estimation coprocessor for use in a video data system. The motion estimation coprocessor may be used with a video memory that subdivides a P row.times.Q column image of pixels into several pages. The page structure enables efficient loading of video data into the coprocessor. The motion estimation coprocessor may perform several block matches simultaneously. The motion estimation coprocessor may perform exhaustive block matching or use a hierarchical search.
