AN AREA TIME-EFFICIENT MOTION ESTIMATION MICRO CORE

Abstract

An efficient micro architecture for motion estimation is proposed. It achieves better time and area performance than 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). Together with a new DCT algorithm, the micro structure is further expanded and tailored to facilitate efficient execution of other video operations like DCT and filtering operations.
