ABSTRACT:
In a power management scheme for a power-consuming (e.g. electronic) device, one of multiple predefined operating parameter sets is selected. Each of the sets comprises multiple operating parameter values for the device. Examples of operating parameters include clock frequency or voltage for example. The selection may be responsive to the detection of an event which warrants a change in a current power consumption state of the device. Any operating parameter value in the selected set that would prevent the device from meeting current operating demands is modified to a new value. The new value may be taken from another operating parameter set. The modified set of parameters is applied to the device in order to change the current power consumption state of the device.
