Abstract
Power sources provide power in a range with a maximum supply voltage provided under zero-load current conditions. Power circuits in an IC receive and aggregate indications of load current from processor circuits in processor circuit clusters and, reduce power consumption in the IC during zero or low load current conditions by generating a voltage control signal to reduce the supply voltage. Reducing the no-load voltage also reduces stress on gate oxides of transistors in the IC to increase oxide longevity. Based on the aggregated load current indications, which is periodically updated, the no-load supply voltage may be incrementally reduced down to a voltage threshold over the course of multiple periods. In some examples, the power circuits receive throttle signals when the processor circuits are throttled due to a voltage droop, and such signals may cause the power circuits to generate a control signal to increase the no-load voltage.
