FASE: Energy Isolation Framework for Latency-Sensitive Applications in Intermittent Systems with Multiple Peripherals
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems(2023)
摘要
The rapid and widespread deployment of Internet of Things (IoT) sensors is limited by issues related to maintenance costs and safe battery disposal. While battery-less systems supported by harvesting ambient energy offer a potential solution, the weakness and instability of ambient energy result in intermittent execution. To provide data consistency, I/O operations are usually performed in the atomic sections, resulting in low-energy efficiency and low-system progress in intermittent systems. To improve application responsiveness and prevent low-energy efficiency due to atomic I/O operations, we propose a framework named FASE, which provides energy isolation assistance to support multiple asynchronous atomic I/O operations in intermittent systems. Our proposal was evaluated on a real platform, and the results show that, compared to state-of-the-art works, our proposed algorithm can increase the rate of completion for latency-sensitive applications by more than 50%.
