无电池系统提供了有前途的平台，以可持续的方式支持无处不在的近传感器智能。这些系统仅依赖于通常提供有限功率的环境能源。设计无电池系统的一种常见方法是使用间歇执行--节点将能量存储到电容存储器中，直到达到阈值电压，数字组件打开并消耗存储的能量，直到能量耗尽并死亡。有限的可用能源需要开发特定于应用和领域的加速器，以实现能源效率和及时性。由于易变状态和间歇性行为之间的关系非常密切，执行实际的系统原型对于证明间歇性系统的可行性至关重要。然而，间歇性加速器没有原型平台。本文介绍了BOBBER，第一个实现的间歇性基于FPGA的加速器原型平台。我们展示了BOBBER在优化和评估仅由RF能量收集供电的神经网络加速器中的应用。
Batteryless systems offer promising platforms to support pervasive, near-sensor intelligence in a sustainable manner. These systems solely rely on ambient energy sources that often provide limited power. One common approach to designing batteryless systems is using intermittent execution---a node banks energy into a capacitive store until a threshold voltage is met and the digital components turn on and consume the banked energy until the energy is depleted and they die. The limited amount of available energy demands the development of application- and domain-specific accelerators to achieve energy efficiency and timeliness. Given the extremely close relationship between volatile state and intermittent behavior, performing actual system prototyping has been critical for demonstrating feasibility of intermittent systems. However, no prototyping platform exists for intermittent accelerators. This paper introduces BOBBER, the first implementation of an intermittent FPGA-based accelerator prototyping platform. We demonstrate BOBBER in the optimization and evaluation of a neural network accelerator powered solely by RF energy harvesting.
