Advanced thermal management using an average power controller over an adjustable time window

An apparatus comprising:

• a target device;
• a source device, the source device to have a thermal influence on the target device;
• and
• a thermal management controller to transmit average power data to the source device based on the thermal influence.

A system comprising:

• a target device;
• a source device, the source device to have a thermal influence on the target device;
• and
• a programmable read only memory (PROM) including a stored set of instructions which if executed are operable to transmit average power data to the source device based on the thermal influence.

A method comprising:

• determining average power data for first power domain having a characteristic with respect to a second power domain, the characteristic being selected from a group comprising a thermal time constant, a thermal mass and an influence factor, the average power data being based on the characteristic;
• determining a time window based on the characteristic, the time window defining an amount of time for determining and controlling an average power consumption of the first power domain;
• transmitting the average power data and the time window to the first power domain;
• narrowing the time window a first time if a temperature of the second power domain exceeds a first temperature threshold;
• narrowing the time window a second time if the temperature exceeds a second temperature threshold, the second temperature threshold being greater than the first temperature threshold.
