Abstract
An embodiment of the present invention provides a voltage comparator that senses the type of processor, unified or split voltage plane coupled to a mother board. Under the control of at least one multiplexer, voltage regulators supply voltage to the processor. If the processor is a unified voltage plane type, the voltage regulators are coupled together in a master/slave configuration to supply a single voltage to the processor. If the processor is a split voltage plane type, the voltage regulators are coupled to together in a master/master configuration where a core voltage regulator supplies a core voltage to the processor, and an I/O voltage regulator supplies an I/O voltage to the processor. This will allow each regulator to be set at a different voltages to accommodate processor types with different core and I/O voltages.
