Abstract
An adaptive block-matching motion estimator for used in a video coding system wherein the adaptive block-matching motion estimator is less in hardware complexity and latency time and is therefore more cost-effective to implement and higher in performance. This adaptive block-matching motion estimator includes a DS array for processing the pixel data of the current image block and the pixel data of the compared image block to thereby obtain a difference vector and a set of weight bits; a compression array having a first output port for outputting a compressed sum vector and a second output port for outputting an associated compressed carry vector, with the difference vector and the set of weight bits from the DS array along with the compressed sum vector and the associated compressed carry vector being taken as the inputs to the compression array; and a complexity-matching (CM) unit for processing the compressed sum vector and the associated compressed carry vector from the compression array to thereby produce the desired motion vector.
