NONVOLATILE PROCESSOR ARCHITECTURE EXPLORATION FOR ENERGY-HARVESTING APPLICATIONS

THIS ARTICLE DISCUSSES THE DESIGN OF NONVOLATILE PROCESSORS (NVPS) FOR BATTERYLESS APPLICATIONS IN THE INTERNET OF THINGS (IOT), IN WHICH AMBIENT ENERGY-HARVESTING TECHNIQUES PROVIDE THE POWER. ACHIEVING RELIABLE, CONTINUOUS, FORWARD COMPUTATION WITH AN UNSTABLE, INTERMITTENT POWER SUPPLY MOTIVATES THE TRANSITION FROM CONVENTIONAL VOLATILE PROCESSORS TO EMERGING NVPS. THIS ARTICLE PROVIDES A GUIDELINE FOR FUTURE IOT APPLICATIONS, REVEALING INHERENT FEATURES OF THE ENERGY-HARVESTING NVP DESIGN.
