Abstract

Aggressive battery shrinkage and its ultimate elimination are a crucial goal for our community, in view of the massive environmental impact of their production and disposal for the expected Trillion of IoT devices that will be deployed in the upcoming decade. From a technological viewpoint, this goal mandates ultra-wide energy adaptation in energy-autonomous integrated systems that are subject to wide variability in power availability, performance target and incoming data context. Adaptation is a prerequisite to assure continuous operation in spite of the limited and widely fluctuating energy source (e.g., battery discharge, harvested power), swift response upon the occurrence of events of interest (e.g., on-chip data analytics), and save energy by leveraging the quality slack offered by the task at hand, while maintaining extremely low consumption in the common case. These requirements have led to the strong demand of a new breed of integrated systems having an extremely wide energy/power scalability and adaptation, beyond conventional voltage scaling. In this talk, new techniques that drastically extend the performance-power scalability of digital circuits and architectures are presented, introducing adapt-ability as replacement of conventional design margining. Silicon demonstrations of better-than-voltage-scaling adaptation to the workload are illustrated for both the data path (i.e., micro-architecture) and the clock path. Adaptation to a very wide range of energy/power availability is also discussed, presenting demonstrations of always-on systems (e.g., microcontrollers, power management units) with power down to sub-nW, and duty-cycled operation down to pW range. Several silicon demonstrations are illustrated to quantify the benefits offered by wide power-performance adaptation, identify opportunities for the decade ahead to drastically reduce the need for batteries, and tackle the environmental challenges that are imposed by “the next trillion batteries”.
