A method for managing power in a data processing system having multiple components includes determining a power budget for the system. Activity levels during a forthcoming time interval are then predicted for each of the components. Using the predicted activity levels, the power budget is allocated among the system components. An activity limit is then established for each component based on its corresponding portion of the power budget. The activity of a component is then monitored and, if the component's activity exceeds the component's corresponding activity limit, constrained. Determining the predicted level of activity may include determining a predicted number of instructions dispatched by a processor component or a predicted number of memory requests serviced for a system memory component. Allocating the power budget includes allocating each component its corresponding standby power and a share of the system power available for dynamic powering based on the expected levels of activity.
A method managing power in a data processing system having at least one processor component and a memory component, comprising:
A computer program product comprising computer executable instructions, stored on a computer readable medium, for managing power in a data processing system having a plurality of components including a processor component and a non-processor component, the instructions comprising:
A data processing system having at least one processor component and a memory component, wherein the system includes a power administrator suitable for:
