  • Patent number: 11768533
    Abstract: Methods and apparatus relating to platform power consumption reduction via power state switching are described. In one embodiment, control logic causes a processor to enter a first low power consumption state (e.g., S0ix) instead of a second low power consumption state (e.g., S3) based on whether a threshold time period exists between a first wake event (e.g., corresponding to a first one of one or more awake requests) and a second wake event (e.g., corresponding to a second one of the one or more awake requests). Other embodiments are also claimed and disclosed.

  • Patent number: 10768680
    Abstract: Methods and apparatuses relating to transactional power management are described. In one embodiment, a hardware apparatus includes a hardware processor having a core, a plurality of power domains to transition to one of a plurality of power states in response to a power management command for each power domain, and a power transaction unit to assign a first power management command as a first power transaction and a second power management command as a second power transaction for concurrent execution, perform a commit of the first power transaction and the second power transaction when there is no conflict between the first power transaction and the second power transaction, and perform an abort of the first power transaction and a commit of the second power transaction when there is a conflict between the first power transaction and the second power transaction.

  • Patent number: 10671404
    Abstract: Dynamic power management of integrated devices can be accomplished using game theory. In an example, power demands for individual devices (e.g., CPU, GPU, communications, etc.) can be controlled by governors. An engine can determine a system condition (e.g., docked or undocked) and use a reward and/or penalty matrix to determine power settings to provide to governors. Periodically, the engine can reevaluate the system condition and power settings for the governors. For example, device components can be modeled as players in a game. In the case of idle power management scenarios, the players can deploy cooperative gaming strategy to allow the system to be in a low power state.

  • Patent number: 10551900
    Abstract: A first optimal CPU frequency that produces minimal power consumption for a CPU/platform combination may be calculated by using an Efficiency Aware Race to Halt (EARtH) algorithm, which ignores the power efficiency curve of the voltage regulator (VR). These results may then be modified by applying the power efficiency curve of the associated VR to determine a second optimal CPU frequency that produces power consumption that is less than the value calculated by the EARtH algorithm.

  • Patent number: 10275853
    Abstract: The present disclosure describes techniques related to media caching. A media hub device may include a media hub device configured to execute an operation on a current frame of media having a frame period. The media hub device may include a cache configured to provide, to a media accelerator of the media hub device, data associated with the frame period of the current frame.

  • Patent number: 10133336
    Abstract: Systems and methods may provide for identifying runtime information associated with an active workload of a platform, and making an active idle state determination for the platform based on at least in part the runtime information. In addition, a low power state of a shared resource on the platform may be controlled concurrently with an execution of the active workload based on at least in part the active idle state determination.
