Briefly, a method an apparatus of a power management system of a semiconductor device capable of managing a power consumption of the semiconductor device by varying an operating voltage of the semiconductor device according to a voltage value based on a reference number.

Method and apparatus to manage power consumption of a semiconductor device

An electronic circuit comprises at least one digital logic circuit; and a power control circuit. The power control circuit is operable to adjust the voltage of a power signal supplied to the at least one digital logic circuit in response to a change in a clock frequency provided to the at least one digital logic circuit. In a further embodiment, the power controller is operable to increase the voltage of the power signal applied to the digital logic circuit before a frequency increase is made, and is operable to decrease the voltage of the power signal applied to the digital logic circuit after a frequency decrease is made.

Frequency-dependent voltage control in digital logic

Method, apparatus and system embodiments are disclosed for one or more programmable registers to hold wakeup time values for power management. For at least one embodiment, information based on the values in the programmable registers may be utilized by a power management unit to determine whether a power island has had sufficient time to transition out of a low power state. The values of the programmable registers may be dynamically modified during operation of a processing system. Other embodiments are also described and claimed.
