Abstract:
1. A system comprising: a central processing unit (CPU); and a graphics processing unit (GPU) coupled to the CPU; wherein power used by the CPU and power used by the GPU are regulated in tandem using a fuzzy logic control system operable for implementing a plurality of fuzzy logic rules, wherein inputs to the fuzzy logic control system include a first value for the power used by the CPU and a second value for the power used by the GPU, wherein the sum of the first value and the second value is compared to a shared supply power and thermal power budget value, and wherein a state of the CPU and a state of the GPU are regulated to maintain the sum within the shared supply power and thermal power budget value; wherein further the first value comprises the power used by the CPU integrated over a period of time, the second value comprises the power used by the GPU integrated over the period of time, and the shared power supply and thermal power budget shared power supply and thermal power comprises an integrated value of the budget over the period of time.
