最近出现了瞬时供电系统的概念：微型无电池嵌入式系统，从环境中获取能量。为了在频繁和不可预测的电源故障的情况下保留信息，瞬时供电系统可以使用非易失性存储器来存储程序状态的检查点。然而，目前的检查点技术只考虑了计算的状态（处理器，存储器），而完全忽略了外围设备的状态。本文提出了一种软件框架，允许使用非平凡的外设，如模数转换器，串行接口或无线电设备，在瞬态供电系统。
Recently has emerged the concept of transiently-powered systems: tiny battery-less embedded systems which harvest energy from their environment. To retain information despite frequent and unpredictable power failures, a transiently-powered system can use non-volatile memory to store checkpoints of program state. However current checkpointing techniques only consider the state of computation (processor, memory) and disregard peripheral state completely. This paper presents a software framework that allows for the use of non-trivial peripherals such as analog-to-digital converters, serial interfaces or radio devices, in transiently-powered systems.
