A new motion estimation algorithm is proposed in this paper.It adaptively selects the full or reduced bit-resolution image for block matching based on the texture complexity of the matching block.In addition

a new telescopic search method using dual-bit-resolution image is adopted.Simulation results show that the proposed algorithm has low computational complexity while achieves good image quality.We have designed a novel systolic-architecture-based search engine that has split data paths.Enhancing the operating parallelism in the low bit-resolution case heightens the throughput.The new motion estimator works at a low clock frequency and a low supply voltage

therefore has lower power consumption.
