\section{Notes}

Execution duration. 
around 10 ms~\cite{reymondSCHEMATIC2024,wuIntOS2024,yildizEfficient2023}.
Several hundreds microseconds~\cite{reymondSCHEMATIC2024}.
Nanoseconds~\cite{wuIntOS2024}.

Using traditional model~\cite{shuklaEnergy2024a}.

Estimating the remaining energy using the energy storage voltage.
In modeling~\cite{houTale2024,kimRapid2024}.
Use energy storage voltage for checkpoint signal~\cite{zengReplayCache2021,balsamoHibernus2015,balsamoHibernus2016,bhattiHarvOS2017,jayakumarQUICKRECALL2014,maengSupporting2019,maengAdaptive2020}.

Power failure injection (soft reset)~\cite{wuIntOS2024,yildizEfficient2023}.

Interrupt using Vdd~\cite{balsamoHibernus2016}.

WCET-based approaches can be extremely pessimistic~\cite{raffeckWoCA2024}.
