Abstract:
A mechanism is provided for using a power proxy unit combined with on-chip actuators to meet a defined power target value identifying a target power consumption of a component of a data processing system. A power manager in the data processing system identifies a proxy power threshold value, for the defined power target value, identifying a maximum power usage for the component, and a power usage estimate value identifying a current power usage estimate for the component. The power manager sends a set of signals to one or more on-chip actuators in the power proxy unit associated with the component in response to the power usage estimate value being greater than the power proxy threshold value. The one or more on-chip actuators adjusts a set of operational parameters associated with the component in order to meet the defined power target value.
