Abstract:
1. A method, in a data processing system, 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 the data processing system, the method comprising: identifying, by a power manager in the data processing system, a power proxy 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, wherein identifying the power usage estimate value for the component further comprises: determining, by the power manager, whether the power usage estimate value is greater than the power proxy threshold value; responsive to the power usage estimate value being greater than the power proxy threshold value, sending, by the power manager, a set of signals to one or more on-chip actuators in the power proxy unit associated with the component; and adjusting, by the one or more on-chip actuators, a set of operational parameters associated with the component in order to meet the defined power target value.
