Abstract: Platform power management includes boosting performance in a platform power boost mode or restricting performance to keep a power or temperature under a desired threshold in a platform power cap mode. Platform power management exploits the mutually exclusive nature of activities and the associated headroom created in a temperature and/or power budget of a server platform to boost performance of a particular component while also keeping temperature and/or power below a threshold or budget.

Abstract: An apparatus includes a processor, a sleep state duration prediction module, and a system management unit. The sleep state duration prediction module is configured to predict a sleep state duration for component of the processing device. The system management unit is to transition the component into a sleep state selected from a plurality of sleep states based on a comparison of the predicted sleep state duration to at least one duration threshold. Each sleep state of the plurality of sleep states is a lower power state than a previous sleep state of the plurality of sleep states.

Abstract: An electronic device includes an accelerated processing unit (APU) and multiple elements. The APU performs operations for a platform boost and throttle (PBT) controller. For the operations, the APU receives a platform electrical power limit, the platform electrical power limit being a limit on a total electrical power allowed to be consumed by a group of the elements at a given time. The APU then determines a present platform electrical power consumption. The APU next adjusts one or more operating parameters for specified elements from among the group of elements to control electrical power consumption by the specified elements based on a relationship between the present platform electrical power consumption and the platform electrical power limit.
