Low Power, Energy Efficient and High Performance Triple Mode Logic for IoT Applications

IoT devices often face conflicting power and performance requirements. They might be required to dynamically switch between (1) power-saving battery-powered mode, (2) ultra-low harvested power mode, and (3) high-performance real-time operation. In this work, we present a novel Triple Mode Logic (TML) that addresses the aforementioned requirements and enables ultra-low power mode for purely harvested operation, energy-saving mode for battery-powered operation, and accelerated mode for high-performance operation. Simulation results of several TML benchmarks indicate that in ultra-low power mode, TML reduces the power consumption by approximately five orders of magnitude compared to CMOS. In normal static (energy-saving) mode, TML consumes up to 35% less energy than Dual Mode Standard Cell (DMSC) state-of-the-art solution. In normal dynamic (high-performance) mode, TML is faster than the DMSC solution by up to 43%.
