由能量收集供电的传感器系统通常包括电池或超级电容器，这会影响系统成本和尺寸，需要时间充电并且不环保。近年来，设计人员提出了一种称为瞬态计算的新概念，旨在去除这些能量存储单元并在断电期间保留系统的状态，以应对不可靠的能源。然而，现有的方法不能保留外部外围设备的状态或者特定于某些外围设备，即它们不是通用的。这张海报提出了一种通用中间件，能够保留通过 SPI 连接到微控制器的外围设备的状态。验证表明，所提出的方法在电源故障之间保留了外设配置，配置外设时的最大时间开销为 15%。然而，对于一个完整的示例应用程序来说，这意味着 0.77% 的开销，低于现有方法造成的开销。
Sensor systems powered by energy harvesting usually include batteries or supercapacitors which impact the system cost and size, need time to be charged and are not environmentally friendly. In recent years, designers have proposed a new concept called transient computing that aims to remove these energy storage units and retain the system’s state between power outages, in order to cope with an unreliable energy source. However, existing approaches cannot retain the state of external peripherals or are specific to certain peripherals, i.e. they are not generic. This poster proposes a generic middleware, capable to retain the state of external peripherals that are connected to a microcontroller through SPI. The validation shows the proposed approach retains the peripheral configuration between power failures with a maximum time overhead of 15% when configuring the peripheral. However, this represents a 0.77% overhead for a complete example application, which is lower than that caused by existing approaches.
