Abstract
A real-time workload scheduling heuristic assigns tasks to the cores such that the total load current consumption of the cores is always less than the total current capability of the under-provisioned on-chip voltage regulators. In addition, the energy-efficient scheduling of the tasks on to the cores ensures that the reconfiguration of the power delivery network is minimized. The heuristic includes DVFS management based on the unique constraints of the under provisioned voltage regulators.
