Cpu/gpu dcvs co-optimization for reducing power consumption in graphics frame processing

A system for minimizing power consumption in graphics frame processing, the system comprising:

• means for initiating graphics frame processing to be cooperatively performed by a central processing unit (CPU) and a graphics processing unit (GPU);
• means for receiving CPU activity data and GPU activity data;
• means for determining a set of available dynamic clock and voltage/frequency scaling (DCVS) levels for the GPU and the CPU;
• and
• means for selecting from the set of available DCVS levels an optimal combination of a GPU DCVS level and a CPU DCVS level, based on the CPU and GPU activity data, which minimizes a combined power consumption of the CPU and the GPU during the graphics frame processing.

A computer program embodied in a computer-readable medium and executed by a processor for minimizing power consumption in graphics frame processing, the computer program comprising logic configured to:

• initiate graphics frame processing to be cooperatively performed by a central processing unit (CPU) and a graphics processing unit (GPU);
• receive CPU activity data and GPU activity data;
• determine a set of available dynamic clock and voltage/frequency scaling (DCVS) levels for the GPU and the CPU;
• and
• select from the set of available DCVS levels an optimal combination of a GPU DCVS level and a CPU DCVS level, based on the CPU and GPU activity data, which minimizes a combined power consumption of the CPU and the GPU during the graphics frame processing.
