Abstract
A method and system of adaptive power control. Characteristics of a specific integrated circuit are used to adaptively control power of the integrated circuit.
Claims21
A method comprising:
- accessing a measurement of a frequency-voltage characteristic of an integrated circuit, wherein the frequency-voltage characteristic is stored external to a substrate of the integrated circuit;
- and
- operating the integrated circuit at a voltage and frequency specified by the frequency-voltage characteristic.
A method comprising:
- determining, independent of operating voltage, a desirable operating frequency for a processor;
- accessing an indication of voltage corresponding to the desirable operating frequency, the voltage selected based upon characteristics that are specific for the processor, wherein the characteristics are stored external to a substrate of the processor;
- and
- operating the individual processor at the voltage.
1 more element
A computer system comprising:
- a processor capable of being operated at a plurality of frequencies and at a plurality of voltages;
- first software for determining an operating frequency for said processor independent of operating voltage;
- second software for determining an operating voltage corresponding to the operating frequency, wherein said determining is based on a frequency-voltage relationship that is specific to the processor and stored externally to the processor;
- and
- third software for commanding the processor to operate at the operating frequency and operating voltage.
2 more elements
