Abstract
A motion estimation circuit and a motion estimation processing element are provided. The latch module in the motion estimation circuit has n pieces of m-stage shift registers. Each shift register receives a current block data and transmits the received current block data to next stage according to a timing. The processing module has a plurality of processing elements (PEs), which are divided into (m+1) groups. The PEs of the i-th group receive the left search window data and the right search window data and are coupled to the input ends and the output ends of the i-th stage of latches, wherein 0<i≦m. Each PE compares the similarity degree between the corresponding candidate block in the search window and the current block and outputs the processed result, respectively. The comparing unit receives and compares the processed results for outputting a first comparison result.
