Abstract
A method and apparatus for efficient motion vector detection is disclosed that provides an expanded search window with a plurality of motion processors. The internal search window of each motion processor is arranged as a set of N row by M column rectangular subblocks. An address generator circuit scans a stream of pixel data values out of a reference frame memory while a set of delay circuits route the stream of pixel data values to the input paths for the internal subblocks and match input timing for the motion processors.
