Abstract
An efficient micro architecture for motion estimation is proposed. It achieves better time and area performance over the existing structures. Through pipelining and effective manipulation of 2's complement arithmetic, the adder complexity is kept to its lowest, while speed for a combined subtraction, absolution and accumulation operations is made as fast as a carry-save addition (CSA).
