ABSTRACT:
In one embodiment, an integrated circuit comprises at least one measurement unit configured to generate an output indicative of a supply voltage at which the integrated circuit is operable for a given operating frequency and a control unit coupled to receive the output. The control unit is configured to generate a voltage control output indicative of a requested supply voltage for the integrated circuit responsive to the output. The voltage control output may be output from the integrated circuit for use by circuitry external to the integrated circuit in generating the supply voltage for the integrated circuit.
