Abstract
A technique to adjust a processor's operating voltage dynamically while preventing a user from placing the processor into a harmful operating voltage state in relation to the core/bus frequency ratio of the processor. More particularly, embodiments of the invention relate to a technique to control the operating voltage of the processor as a function of the processor's bus and/or core clock frequency.
