摘要

提出了顺序电路中峰值功率的新测量方法。本文给出了一种自动程序来获得这些度量的很好的下界以及达到这种下界的实际输入向量。电路的初始状态是决定顺序电路中开关活动量的一个重要因素,必须加以考虑。利用遗传技术开发了峰值功率估计工具K2。实验表明,由K2生成的矢量序列比随机生成的序列给出更准确的峰值功耗估计。

K2: an estimator for peak sustainable power of VLSI circuits
New measures of peak power in the context of sequential circuits are proposed. This paper presents an automatic procedure to obtain very good lower bounds on these measures as well as the actual input vectors that attain such bounds. The initial state of the circuit is an important factor in determining the amount of switching activity in sequential circuits and is taken into account. A peak power estimator tool K2 was developed using genetic techniques. Experiments show that vector sequences generated by K2 give much more accurate estimates for peak power dissipation than the estimates made from randomly generated sequences.
