  • Power management architecture for defining component power states under a global power state and maintaining a power state floor for a specified component if a power state for the specified component under a new global power state is below the power state floor
    Patent number: 7065659
    Abstract: A method and power management infrastructure are disclosed that facilitate implementing application power requirements-derived device power state schemes, on a computing device comprising a plurality of component devices managed by device drivers. The disclosed power management framework includes a set of global power state definitions specifying, for each global power state, default power states for the component devices. The infrastructure also includes a power manager. The power manager includes an application interface including a function for registering device-specific requirements associated with particular applications executing on the computing device. The power manager also includes a device power state set function facilitating issuing a device-specific command setting a power state of a specified component device.

  • Power management architecture for defining component power states under a global power state and applying a new component power state when a new component power state is greater than a registered power state floor
    Patent number: 7055046
    Abstract: A method and power management infrastructure are disclosed that facilitate implementing application power requirements-derived device power state schemes, on a computing device comprising a plurality of component devices managed by device drivers that are capable of requesting lower power states without affecting other component device power states. The disclosed power management framework includes a set of global power state definitions specifying, for each global power state, default power states for the component devices. The infrastructure also includes a power manager. The power manager includes an application interface including a function for registering device-specific requirements associated with particular applications executing on the computing device. The power manager also includes a device power state set function facilitating issuing a device-specific command setting a power state of a specified component device.

  • Power profiling
    Publication number: 20040268159
    Abstract: Systems and methods are described for profiling the power consumption of software instructions executing on a processor. A power measurement circuit records power consumption levels of a processor executing various software instructions. A profiling tool tracks and identifies the instructions being executed on the processor and generates an association between the instructions and the power consumed during execution of those instructions. The power profile enables the precise isolation and identification of instructions relative to amounts of power consumed during the execution of those instructions.
