在一种基于望远镜搜索的块匹配运动估值的VLSI实现中，对用于加速搜索的传统心动阵列引擎进行了结构上的改进，从而能够显著地降低功耗.方法是使用一种新的块匹配误差计算的提早跳出技术，并通过在阵列处理单元中屏蔽操作数来避免不必要的计算操作.基于算法模拟结果的简单估计表明：使用新结构搜索引擎的运动估值，功耗可降低到原来的40％左右，而仍然保持着相同的处理速度和相似的视频解码图质量.

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.
