Circuits and Systems Advances in Near Threshold Computing

Modern society is witnessing a sea change in ubiquitous computing in which people have embraced computing systems as an indispensable part of day-to-day existence. Computation storage and communication abilities of smartphones for example have undergone monumental changes over the past decade. However global emphasis on creating and sustaining green environments is leading to a rapid and ongoing proliferation of edge computing systems and applications. As a broad spectrum of healthcare home and transport applications shift to the edge of the network near-threshold computing (NTC) is emerging as one of the promising low-power computing platforms. An NTC device sets its supply voltage close to its threshold voltage dramatically reducing the energy consumption. Despite showing substantial promise in terms of energy efficiency NTC is yet to see widescale commercial adoption. This is because circuits and systems operating with NTC suffer from several problems including increased sensitivity to process variation reliability problems performance degradation and security vulnerabilities to name a few. To realize its potential we need designs techniques and solutions to overcome these challenges associated with NTC circuits and systems. The readers of this book will be able to familiarize themselves with recent advances in electronics systems focusing on near-threshold computing.
