There is growing interest in deploying energy harvesting processors and accelerators in Internet of Things (IoT). Energy harvesting harnesses the energy scavenged from the environment to power a system. Although it has many advantages over battery-operated systems such as lightweight, compact size, and no necessity of recharging and maintenance, it may suffer frequently power-down and a fluctuating power supply even with power on. Non-volatile processor (NVP) is a promising architecture for effective computing in energy harvesting scenarios. Recently, non-volatile accelerators (NVA) have been proposed to perform computations of deep learning algorithms. In this paper, we overview the recent studies of NVP and NVA across the layers of hardware, architecture, software and their co-design. Especially, we present the design insights of how the state-of-the-art works adapt their specific designs to the intermittent and fluctuating power conditions with the energy harvesting technology. Finally, we discuss recent trends using NVP and NVA in energy harvesting scenarios.
