Abstract
Methods and apparatus for facilitating motion estimation in video processing are provided. Preferably, coordinates of a search area within a video frame are determined for each of a plurality of macroblocks (MBs) of a reference frame based upon a predicted location derived from the coordinates of the MB within the reference frame and motion estimation information. The video frame can be segmented into tiles and associated overlapping tile defined for at least some tiles. Search data is defined for each tile as pel data for each pixel within that tile and any associated tile. Macroblock searches are preferably conducted on a tile assignment basis with tile search assignments distributed among a plurality of processing elements. Each processing element preferably has a local memory it uses for the search data when performing a tile search assignment.
