Abstract
Improvement of energy efficiency is indispensable for computer systems in our rapidly evolving information society. To reduce energy consumption without performance degradation, aggressive and careful power management is necessary. Simple power gating cannot fully take the chances of power reduction since volatile memories lose data when power supply is off. However, with new non-volatile memories (NVMs), a synergetic effect for drastic energy reduction is highly expected. Normally-off computing is a way of computing where inactive components of computer systems are aggressively powered off with the help of new NVMs. As a result, high attention has been paid to normally-off computing using these NVMs and cooperation among algorithm, OS, compiler, architecture, circuit and device.
