摘要： A system and method for efficient management of operating modes within an IC for optimal power and performance targets. On a same die, an SOC includes one or more processing units and a input/output (I/O) controller (IOC). The multiple interfaces within the IOC manage packets and messages according multiple different protocols. The IOC maintains an activity level for each one of the multiple interfaces. This activity level may be based at least on a respective number of transactions executed by a corresponding one of the multiple interfaces. The IOC determines a power estimate for itself based on at least the activity levels. In response to detecting a difference between the power estimate and an assigned I/O power limit for the IOC, a power manager adjusts at least respective power limits for the one or more processing units based on at least the difference.

摘要： A method and system for real-time prediction of power usage for a change to another performance state provides input data for power management decision-making processes or for display to system operators. The unit(s) for which power usage is predicted may be a single processor in a uni-processor system or may extend up to the level of facilities within a complex of processing facilities. The method and system gather real-time data on the power consumption of the unit(s) and create a model, such as a regression model, of power versus performance. A resulting power usage change required by a prospective nominal performance state change is shown as display data, or is transmitted to a power budgeting controller to inform the controller as to potential changes that can enhance system operation, such as managing tradeoffs of power allocated to various sub-units of a processing system.
