This book provides a practical guide for engineers doing low power System-on-Chip (SoC) designs. It covers various aspects of low power design from architectural issues and design techniques to circuit design of power gating switches. It also describes some well established techniques and then details the latest approaches to low power design. These leading edge techniques include power gating and adaptive voltage scaling. In addition to providing a theoretical basis for these techniques, the book addresses the practical issues of implementing them in today's designs with today's tools. All of the methods used have been proven in test chips jointly developed by Synopsys and ARM.

Provides practical implementation guidelines for the practicing engineer Explains key decisions that need to be made in implementing low power designs, why they were made and what results were obtained in actual silicon Describes test chips and methods jointly developed by Synopsys and ARM Includes supplementary material: sn.pub/extras
