从收获源操作的系统通常集成电池或超级电容器，以平滑收割机输出的快速变化。然而，这样的能量存储装置需要时间来充电，并且增加了系统的尺寸、质量和成本。最近解决这个问题的方法是直接从采集器输出为系统供电，称为瞬态计算。为了解决由于功率循环而必须从开始重新开始计算的问题，已经提出了许多技术来处理瞬态功率源。在本文中，我们定量评估三个国家的最先进的方法在德州仪器MSP430微控制器的应用场景，每个表现最好的特点。最后，建议系统设计人员选择最合适的方法。
Systems operating from harvested sources typically integrate batteries or supercapacitors to smooth out rapid changes in harvester output. However, such energy storage devices require time for charging and increase the size, mass and cost of the system. A recent approach to address this is to power systems directly from the harvester output, termed transient computing. To solve the problem of having to restart computation from the start due to power-cycles, a number of techniques have been proposed to deal with transient power sources. In this paper, we quantitatively evaluate three state-of-the-art approaches on a Texas Instruments MSP430 microcontroller characterizing the application scenarios where each performs best. Finally, recommendations are provided to system designers for selecting the most suitable approach.
