System for adaptive -power consumption design in ultrathin computing devices

A method for adaptive power consumption, in a computing device including a chassis forming an enclosure forming a chamber, the computing device further includes in the chamber a heterogeneous processing unit that includes a CPU operatively coupled with a GPU and that generates thermal and performance information for the CPU and GPU, a memory, a memory controller that connects the memory to the heterogeneous processing unit, a passive cooling subsystem that draws heat from the heterogeneous processing unit, an active cooling subsystem that cools off the chamber, a plurality of thermal sensors positioned to monitor temperatures within the chamber relating to the heterogeneous processing unit, the passive cooling subsystem and the active cooling subsystem, comprising:

• receiving thermal and performance information from the heterogeneous processing unit and the plurality of thermal sensors;
• and
• responsively adjusting overall power consumption of the heterogeneous processing unit, the memory controller, the memory and the active cooling subsystem to maintain performance of the heterogeneous processing unit while minimizing thermal heating.

A computer readable non-transitory medium including instructions which when executed in a processing system cause the system to provide adaptive power consumption, in a computing device including a chassis forming an enclosure forming a chamber, the computing device further includes in the chamber a heterogeneous processing unit that includes a CPU operatively coupled with a GPU and that generates thermal and performance information for the CPU and GPU, a memory, a memory controller that connects the memory to the at least one heterogeneous processing unit, a passive cooling subsystem that draws heat from the heterogeneous processing unit, an active cooling subsystem that cools off the chamber, a plurality of thermal sensors positioned to monitor temperatures within the chamber relating to the heterogeneous processing unit, the passive cooling subsystem and the active cooling subsystem, comprising:

• receiving thermal and performance information from the heterogeneous processing unit and the plurality of thermal sensors;
• and
• responsively adjusting overall power consumption of the heterogeneous processing unit, the memory controller, the memory and the active cooling subsystem to maintain performance of the heterogeneous processing unit while minimizing thermal heating.
