Abstract
In this paper, a power delivery system for homogeneous chip multi-processor (CMP) systems is proposed. The power delivery system is modified at run time by clustering multiple on-chip voltage regulators (OCVR) depending on the power demand of the workload. The OCVRs are designed to deliver up to the average current requirement of the typical workloads executed on the CMP platform. When the current demand of a core cluster exceeds the average value, the output of multiple OCVRs is combined through a high-speed switch network to provide the necessary current. Two OCVR topologies (Buck and LDO) are analyzed to characterize the impact on the characteristics of the voltage regulator as the peak load current is reduced. Simulation results for run-time OCVR clustering indicate a 36% reduction in the energy consumption of the system at an average load current with improvement in the load regulation. In addition, the area occupied by the OCVRs is reduced by at least 70%.
