Title: System Design and Optimization for Energy Harvesting Powered Devices

Abstract:

Wearable, implantable and Internet of Thing devices are attracting increasing attention from both research and industry fields. Energy harvesting is a promising alternative of battery to power these embedded systems. However, the intrinsic instability of energy harvesting systems leads to potential frequent power interruptions. In traditional volatile processor, all the status will be lost at power failures and the program needs to re-start after power resumes. In order to survive the power failures and enable accumulative execution, non-volatile memory is proposed to be used for backing up volatile information before power depletion and recovering the system status after power resumes. In this talk, I will summarize our recent work on system design and optimization for energy harvesting powered devices, targeting at energy efficient program execution on these kinds of systems.
