Abstract
Methods and mechanisms to simultaneously regulate two or more supply voltages provided to an integrated circuit by a voltage regulator. In an embodiment of the invention, a voltage regulation message exchanged between the integrated circuit and the voltage regulator includes an identifier indicating two or more supply voltages selected from a plurality of supply voltages provided to the integrated circuit by the voltage regulator, where the voltage regulation message relates to the indicated two or more supply voltages. In another embodiment, the voltage regulation message indicates a desired supply voltage level to which the indicated two or more supply voltages are to transition.
