A Semi-Dynamic Resource Management Framework for Multicore Embedded Systems with Energy Harvesting
Abstract: Solar energy harvesting systems are an important class of embedded systems that utilize solar energy to perform computations without relying on an external power supply or frequent battery charges. Due to the variable nature of solar energy harvesting, the deployment of an intelligent and low-overhead run-time energy management strategy is not only beneficial but also essential for meeting system performance and energy-efficiency goals. This dissertation proposes novel heuristics and algorithms for workload allocation, scheduling, and platform management on multicore embedded systems powered by solar energy harvesting to maximize performance for a given harvested energy budget. Our framework is flexible and comprehensive: it considers multiple additional design constraints related to temperature, soft error reliability, and aging; and is applicable on both homogeneous and heterogeneous multicore platforms.
