低功耗数字系统设计方法

Low Power Design Methodology

首先对集成电路的功耗来源进行简要的分析 .在此基础上 ,按照不同的设计层次 ,分别介绍了系统层、寄存器传输层、版图层的各种主要的低功耗设计技术 ,重点分析了不同技术的基本思路和进一步发展的方向 .最后 ,从整体设计流程的角度介绍了前馈型的设计方法 。

The need to reduce the power consumption of the next generation of digital systems is clearly recognized with the increasing application of portable device and high performance system. The power sources of the VLSI are analyzed. This paper surveys a range of power optimization techniques used at different levels of design abstraction and the top down low power design methodology. A forward feed design flow is introduced and the importance of the higher level power optimization of design abstract is illustrated.
