Abstract
One example discloses an apparatus for power management, including: a circuit having a first power-domain and a second power-domain; wherein the first and second power-domains include a set of operating parameter values; a circuit controller configured to incrementally sweep at least one of the operating parameter values of the first power-domain; a circuit profiler configured to derive a total power consumption profile of the circuit based on the circuit's response to the swept operating parameter value; wherein the circuit controller sets the operating parameter values for the first and second power-domains based on the total power consumption profile of the circuit.
Claims13
An apparatus for power management, comprising:
- a circuit having a first power-domain and a second power-domain;
- wherein the first and second power-domains include a set of operating parameter values;
- a circuit controller configured to incrementally sweep at least one of the operating parameter values of the first power-domain;
- and
- a circuit profiler configured to derive a total power consumption profile of the circuit based on the circuit's response to the swept operating parameter value;
- wherein the circuit controller sets the operating parameter values for the first and second power-domains based on the total power consumption profile of the circuit.
A method for power management in a circuit having a first power-domain and a second power-domain, wherein the first and second power-domains include a set of operating parameter values, the method comprising:
- incrementally sweep at least one of the operating parameter values of the first power-domain;
- deriving a total power consumption profile of the circuit based on the circuit's response to the swept operating parameter value;
- and
- setting the operating parameter values for the first and second power-domains based on the total power consumption profile of the circuit.
An article of manufacture including at least one non-transitory, tangible machine readable storage medium containing executable machine instructions for power management, comprising:
- wherein the article includes,
- a circuit having a first power-domain and a second power-domain;
- wherein the first and second power-domains include a set of operating parameter values;
- wherein the instructions include,
- incrementally sweep at least one of the operating parameter values of the first power-domain;
- deriving a total power consumption profile of the circuit based on the circuit's response to the swept operating parameter value;
- and
- setting the operating parameter values for the first and second power-domains based on the total power consumption profile of the circuit.
