Claim:
1. A system comprising: a plurality of instances of a component, wherein each instance is operable in a plurality of modes; a control circuit coupled to the plurality of instances of the component, wherein the control circuit is configured to detect that one or more of the plurality of instances of the component is operating in a first mode of the plurality of modes, wherein the first mode excludes worst-case power supply load for which a voltage margin is established in a power supply voltage magnitude programmed into the system for supply to the plurality of instances of the component, and wherein the control circuit is configured to request a reduced power supply voltage magnitude responsive to detecting that the one or more of the plurality of instances of the component are operating in the first mode, wherein a given power supply load causes voltage droop in the power supply voltage experienced by the plurality of instances of the component, and wherein a lack of the worst-case power supply load indicates that the voltage droop is less than a second power supply droop associated with the worst-case power supply load and accounted for in the voltage margin.
