Abstract:
1. An integrated circuit comprising: 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, wherein the measurement unit is configured to generate the output continuously while the integrated circuit is in operation at the given operating frequency; and a control unit coupled to receive the output from the measurement unit and configured to generate a voltage control output indicative of a requested supply voltage for the integrated circuit, wherein the control unit is configured to generate the voltage control output responsive to the output of the measurement unit, wherein the voltage control output is output by the integrated circuit for use by circuitry external to the integrated circuit to generate the supply voltage for the integrated circuit, wherein the control unit is configured to generate the voltage control output for a requested supply voltage different from a current supply voltage while the integrated circuit is operating at the given operating frequency.
