Abstract
For one embodiment of the present invention, a processor may include one or more integrated voltage regulators powered by an external voltage regulator and generating one or more local supply voltages for the processor. The one or more local supply voltages may be set to allow one or more circuits powered by the local supply voltage(s) to meet a timing requirement. The local supply voltage(s) may be adjusted by the processor in accordance with a power management policy.
Claims18
A processor comprising:
- a voltage regulator to be powered by a first voltage and to provide a second voltage;
- and
- a circuit powered by the second voltage.
A computer system comprising:
- a discrete voltage regulator to provide a global Vcc;
- and
- a processor including a local voltage regulator to be powered by the global Vcc and to provide a local Vcc for the processor.
A method comprising:
- providing a first voltage to a processor comprising an integrated voltage regulator;
- powering the voltage regulator with the first voltage, the voltage regulator to provide a second voltage;
- and
- powering at least a portion of the processor with the second voltage.
