Smart Grid on Chip: Work Load-Balanced On-Chip Power Delivery.

In this paper, a dynamic on-chip power delivery system for chip multiprocessors (CMPs) is proposed, analogous to the smart grid deployed for large-scale energy distribution. The system includes underprovisioned on-chip voltage regulators (VRs) interconnected through a switch network. The peak current rating of the VRs is selected to meet only the average current demand of the cores. A real-time lo...
