- \section{Conclusion}
- When designing software supports for intermittent systems, designers rely on an execution model that abstracts the hardware-level operations and describes the key behaviors of the system.
- However, the traditional model is failing to accurately model the actual behaviors as recent systems target smaller energy storages and more power-demanding architectures.
- In this paper, we propose a new execution model, which incorporates the major source of this inconsistency: the buffering effects due to the system's inherent capacitance.
- Our model reveals that the traditional model can mislead the power efficiency of the system up to 5.62x and also may lead to unsafe checkpoint executions.
- Also, we propose several design guidelines, including methods to predict imminent power failure more accurately, which can improve the performance of existing checkpoint techniques up to 3.04x.
