  • Patent number: 10289189
    Abstract: A supervisory control system provides power management in an electronic device by providing timeout periods for a hardware component to lower levels of the operating system such as a power management arbitrator and/or a hardware interface controller. The timeout periods are chosen based on usage patterns detected on the electronic device and based on user preference information. The power management arbitrator and/or hardware interface controller transition at least a portion of a hardware component to a lower-power state based on monitored activity information of the hardware component. The supervisory control system may further provide wakeup periods to the power management arbitrator and/or a hardware interface controller to determine whether the hardware component should be transitioned to a higher power state at the end of the wakeup period if the hardware component satisfies a transition condition.

  • Patent number: 10248613
    Abstract: Data bus activation in an electronic device is provided. In one aspect, a host circuit determines a cumulative potential representing a cumulative fractional bus activation vote on a data line(s) in the data bus. The host circuit activates the data bus when the cumulative potential is greater than a configurable bus activation threshold. In another aspect, a device circuit(s) determines a selected signal strength threshold that is less than determined signal strength of an incoming signal. Accordingly, the device circuit(s) asserts a fractional potential corresponding to the selected signal strength threshold on the data line(s) as a fractional bus activation vote in the cumulative fractional bus activation vote. By activating the data bus based on the cumulative fractional bus activation vote, the host circuit can support timely data bus activation while preventing the data bus from being falsely activated, thus improving robustness of data bus activation in the electronic device.

  • Patent number: 10241798
    Abstract: An issue control unit is configured to control the rate at which an instruction issue unit issues instructions to an execution pipeline in order to avoid spikes in power drawn by that execution pipeline. The issue control unit maintains a history buffer that reflects, for N previous cycles, the number of instructions issued during each of those N cycles. If the total number of instructions issued during the N previous cycles exceeds a threshold value, then the issue control unit throttles the instruction issue unit from issuing instructions during a subsequent cycle. In addition, the issue control unit increases the threshold value in proportion to the number of previously issued instructions and based on a variety of configurable parameters. Accordingly, the issue control unit maintains granular control over the rate with which the instruction issue unit “ramps up” to a maximum instruction issue rate.

The back-end circuit is coupled to the controller, capable of switching between a first mode and a second mode to control transition of the driving signal by different schemes. The back-end circuit switches from the second mode to the first mode when a mode-switch criterion is satisfied, and whether the mode-switch criterion is satisfied is independent of a measurement of the output voltage.

  • Patent number: 10200303
    Abstract: Various methods and systems for implementing resource management for an infrastructure are provided. Resource management includes datacenter byproduct management interfaces, datacenter power management, datacenter operations optimization and infrastructure resource management. Resource management facilitates using and distributing physical resources, including incidental physical resources that are generated during operation of an infrastructure, based on a minimum threshold reserve of the physical resource associated with the operating the infrastructure. Resource management can include controlling an amount of the physical resource that is generated and an amount the physical resource that is reserved. The minimum threshold reserve in combination with the control over generating and reserving the physical resource help identify an allocable amount of the physical resource. Physical resources of an infrastructure are quantified to support resource management.

  • Patent number: 10185385
    Abstract: A method and apparatus to reduce the idle link power in a platform. In one embodiment of the invention, the host and its coupled endpoint(s) in the platform each has a low power idle link state that allows disabling of the high speed link circuitry in both the host and its coupled endpoint(s). This allows the platform to reduce its idle power as both the host and its coupled endpoint(s) are able to turn off their high speed link circuitry in one embodiment of the invention.

  • Patent number: 10176009
    Abstract: A system for optimizing energy efficiency of an embedded system. A hardware abstraction layer (HAL) is coupled to hardware of an embedded system. An energy hardware abstraction layer (eHAL) couples to the hardware and to the HAL. A hypervisor couples to the HAL and to the eHAL. One or more applications couple to the hypervisor, the HAL and the eHAL. The eHAL measures energy use of the embedded system, constructs a model of energy use of the embedded system and, using the model, determines how to one of reduce and minimize energy use of the embedded system. The hypervisor is configured to alter one or more hardware parameters to one of reduce and minimize energy use of the embedded system as the embedded system performs one or more tasks. In implementations a real time operating system (RTOS) is coupled to the one or more applications and to the hypervisor.
