Title
Sytare: a Lightweight Kernel for NVRAM-Based Transiently-Powered Systems
Abstract
In a near future, energy harvesting is expected to replace batteries in ultra-low-power embedded systems. Research prototypes of such systems have recently been proposed. As the power harvested in the environment is very low, such systems need to cope with frequent power outages. They are referred to as transiently-powered systems (TPS). In order to execute non-trivial applications, TPS need to retain information between power losses. To achieve this goal, emerging non-volatile memory (NVM) technologies are a key enabler: they provide a lightweight solution to retain, between power outages, the state of an application and of its peripheral devices. These include sensors, serial interface or radio devices for instance. Existing works have described various checkpointing mechanisms to adapt embedded applications to TPS but the use of peripherals was not yet handled. in these works. This paper proposes a solution for embedded applications using any peripheral device to run despite transient power. We follow a kernel-oriented approach resulting in minimal impact on the programming model of the application. We implement the new concepts in our lightweight kernel called Sytare, running on an MSP430FR5739 micro-controller and we analyze the cost of the proposed solution.
