Functional block level thermal control

A method comprising:

• receiving temperature readings from each of a plurality of functional units implemented on an integrated circuit die;
• determining if a temperature reading from any of the plurality of functional units exceeds a first threshold value;
• and
• if the temperature exceeds the first threshold value for a particular one of the plurality of functional units, performing a first temperature control action on the particular one of the plurality of functional units independently of other ones of the plurality of functional units.

A processor comprising:

• a plurality of functional units, the plurality of functional units including a first processor core, a second processor core, and a northbridge unit;
• and
• a temperature control unit, wherein the temperature control unit is coupled to receive readings indicative of a temperature of each of the plurality of functional units;
• and
• wherein, if the temperature exceeds a first threshold value for a particular one of the plurality of functional units, the temperature control unit is configured to perform a first temperature control action on the particular one of the plurality of functional units independently of other ones of the plurality of functional units.
