Package power zone for limiting power consumption even when individual consumers do not exceed individual limits

A system comprising:

• a plurality of components integrated into one or more integrated circuits that are packaged in a package;
• a power manager that monitors an observable power consumption in the package, during use, wherein the observable power consumption includes power consumed by a plurality of the plurality of components;
• a peak power controller that detects, during use, that a first component of the plurality of components is consuming power that exceeds a first power consumption target assigned to the first component, and the peak power controller triggers one or more first mitigation operations on the first component to reduce the power consumption of the first component in response to detecting that first component is consuming power that exceeds the first power consumption target, wherein the first component is one of a first subset of one or more components within the plurality of components for which first power consumption targets are assigned;
• and
• a package power controller that detects, during use, that the observable power consumption exceeds a second power consumption target for the package, wherein the observable power consumption exceeding the second power consumption target is possible even if power consumed in the components of the first subset are less than the first power consumption targets assigned to the components of the first subset, wherein the package power controller triggers one or more second mitigation operations to reduce power consumption in one or more second components of the plurality of components responsive to the observable power consumption exceeding the second power consumption target.

A system comprising:

• a plurality of components, wherein one or more of the plurality of components implement one or more mitigation operations that are invoked to control power consumption in the one or more of the plurality of components;
• a first power controller configured to invoke a first mitigation operation on a first component of the one or more of the plurality of components responsive to the power consumption of the first component exceeding a first power consumption target assigned to the first component;
• and
• a second power controller configured to invoke the first mitigation operation of the first component responsive to an observable power consumption in the plurality of components exceeding a second power consumption target, wherein the second power controller invoking the first mitigation operation is performed based on the observable power consumption exceeding the second power consumption target even in the event that the plurality of components are consuming power at less than respective first power targets assigned to respective components of the plurality of components.
