%X An architectural enhancement is presented to reduce the power consumption of the telescopic search block-matching motion estimation based on a novel early-jump-out technique for computing block-matching errors.Augmenting it to the conventional systolic-architecture-based VLSI engine for the telescopic search can avoid unnecessary computations.A simple estimation based on the algorithm simulation results shows that,our enhanced architecture consumes 40% as much power as the conventional architecture.Meanwhile,the same throughput and a similar image quality are maintained.
