Closing the Power Gap Between ASIC and Custom

This book carefully details design tools and techniques for realizing low power and energy efficiency in a highly productive design methodology. Important topics include: Microarchitectural techniques to reduce energy per operation; Power reduction with timing slack from pipelining; Analysis of the benefits of using multiple supply and threshold voltages; Placement techniques for multiple supply voltages; Verification for multiple voltage domains; Improved algorithms for gate sizing, and assignment of supply and threshold voltages; Power gating design automation to reduce leakage; and Relationships among tatistical timing, power analysis, and parametric yield optimization. Design examples illustrate that these techniques can improve energy efficiency by two to three times.
