摘　　要：基于运动估计算法的PE模块的硬件结构设计,文中提出了集群式电压调节算法,给电路分配双电压供电,相较于使用单一电压的电路,功耗减少了45.3%.在此基础上,进一步采用门控时钟技术来对电路精细化管理,取得了63.2%的功耗节省.此外,针对多电压电路结构,提出了一种新的电平转化器以获得更小的功耗和延时.According m the hardware structure of the PE module of Motion Estimation circuits, we firstly present the algorithm named Clustered Voltage Scaling （CVS） which is used for assigning the voltage supply to gates in intcgratecl circuits having dual power supplies. Comparing to the original circuit with the single power supply, it provides up to 45.3 96 power reduction. On the basis of the dual VDD circuit, we gate the clock and it shows up to 63.2% power savings. Furthermore, we present a new level conversion to obtain less power and delay for the circuits having multi - power supplies.
