Methods and apparatuses for operating a data processing system

A method performed by a data processing system, the method comprising:

• receiving load information about processing loads for one or more processing units;
• receiving, from one or more thermal sensors, the mal data about the data processing system;
• transitioning between multiple power states for each of the one or more processing units based on the load information and the thermal data, the multiple power states including multiple states with different processor voltages or processor frequencies, and wherein the data processing system is configured to transition to a lower power state to reduce heat produced by the data processing system;
• throttling thread scheduling based on the load information.

A data processing system comprising:

• a plurality of processing units;
• a memory coupled to the plurality of processing units;
• one or more thermal sensors coupled to at least one of the plurality of processing units;
• and
• wherein the memory stores an operating system which receives thermal data about the data processing system and obtains load information about processing loads on the plurality of processing units, and wherein the operating system causes each processing unit in the plurality of processing units to transition independently between multiple power states based on the load information and the thermal data, and the operating system throttles thread scheduling based on the load information.
