Off and On Again: Optimising Intermittently-Powered Systems

Based primarily at ARM, Cambridge

ARM: James Myers and Stephan Diestelhorst
University of Southampton: Alex Weddell and Geoff Merrett

Powering billions of Internet of Things (IoT) nodes will be a significant challenge: batteries increase cost, environmental impact and maintenance. Energy harvesting (EH) scavenges power from sources such as light, vibration, or temperature difference. EH sensor nodes are now being deployed with a battery topped up to smooth out temporal variations in EH and ensure reliable operation. A recent competing approach proposes nodes with no energy storage, which only operate when power is available, maintaining their state in non-volatile memory (NVM) between intermittent power cycles. Such systems either use a purely software approach (taking regular program state checkpoints in NVM) or purely hardware (with all state being in NVM). This project proposes to explore and demonstrate a HW/SW co-design strategy to maximise the amount of useful computation per power-cycle through optimising software structures and the use of NVM.

The 3.5 year studentship offered includes both tuition fees (UK/EU students) and an annual tax-free stipend of £17000 pa for living costs (EU students will almost certainly be eligible, see
