Patent ID: 8135966

Claim:
A method for power management, the method comprise: receiving an indication about a load of a circuit; determining at least one long-term activation parameter in view of a circuit load pattern during at least one long period; determining at least one short-term activation parameter in response to an expected or detected short period load change of the circuit, wherein the at least one short-term activation parameter includes a short-term voltage/frequency increment point and a short-term voltage/frequency decrement point during a short-term that corresponds to an execution period of a task; providing at least one clock signal and at least one supply voltage in response to the long-term activation parameter and in response to the short-term supply parameter; and determining a short-term voltage/frequency alteration point and determining a conditional voltage/frequency alteration point in which a voltage/frequency alteration is responsive to the load of the circuit based on the conditional voltage/frequency alteration point.
