Near Threshold Computing: Technology, Methods and Applications

Abstract

This book explores near-threshold computing (NTC), a design-space using techniques to run digital chips (processors) near the lowest possible voltage. Readers will be enabled with specific techniques to design chips that are extremely robust, tolerating variability and resilient against errors. Variability-aware voltage and frequency allocation schemes will be presented that will provide performance guarantees, when moving toward near-threshold manycore chips. Provides an introduction to near-threshold computing, enabling reader with a variety of tools to face the challenges of the power/utilization wall, Demonstrates how to design efficient voltage regulation, so that each region of the chip can operate at the most efficient voltage and frequency point, Investigates how performance guarantees can be ensured when moving towards NTC manycores through variability-aware voltage and frequency allocation schemes.
