In this paper, the authors propose a novel framework for energy and workload management in multi-core embedded systems with solar energy harvesting and a periodic hard real-time task set as the workload. Compared to prior work, their energy management framework possesses several advantages, including a battery-supercapacitor hybrid energy storage module for more efficient system energy management, a semi-dynamic scheduling heuristic that continuously adapts to run-time harvested power variations without losing the consistency of the periodic task set and a coarse-grained core shutdown heuristic for additional energy savings.
