基于结构级的低功耗设计方法

Low Power Design in Structure Level

随着移动设备需求量的不断增大和芯片工作速度的不断提高 ,芯片的功耗已经成为电路设计者必须考虑的问题 ,对于芯片整体性能的评估已经由原来的面积和速度的权衡变成面积、时序、可测性和功耗的综合考虑 ,并且功耗所占的权重会越来越大 .文中主要讲述通过不同方法在进行结构设计时如何实现低功耗设计 ,比如采用并行结、流水结构。

When more and more mobile equipments are needed and the frequency of chips is increased, the power of chips are more and more considered by designers. The evaluation of the total performance of chips is changed from areas and speed of chips to areas ,timing ,testability and power of chips ,and power will play more and more important role in the total performance.In this paper, we mainly discuss how to implement low power designs in different ways in structure level, for examples,using parallel structure, pipeline structure ,optimizing coding style, etc. .
