Abstract: Systems, apparatuses, and methods for implementing runtime-learning graphics power optimization are illustrated. A system management unit monitors tasks queued for a computing component, such as a central processing unit (CPU) or a graphics processing unit (GPU). The system management unit computes a total number of clock cycles consumed to execute a first task. The system management unit then determines a second task for execution and modifies a current operating frequency by a given percentage while executing the second task. The system management unit determines the number of clock cycles that execution of the second task consumed and compares this to the number of clock cycles for the first task. Based at least in part on the comparison, the system management unit computes a performance sensitivity of tasks similar to the first and second tasks.

Abstract: Systems, apparatuses, and methods for implementing efficient power optimization in a computing system are disclosed. A system management unit records operating frequencies required for a computing component to execute a first task. The system management unit stores the recorded operating frequencies in a data array or any other predetermined memory location of a computing system. The system management unit uses the recorded operating frequencies to determine operating frequencies for execution of one or more other tasks.

Abstract: Systems, apparatuses, and methods for managing power and performance in a computing system. A system management unit detects a condition indicating a change in a power-performance state of a given computing unit is indicated. In response to detecting the indication, the system management unit is configured to initiate a change to a frequency of a clock signal generated by an adaptive oscillator by changing a voltage supplied to the adaptive oscillator. The adaptive oscillator is configured to rapidly change a frequency of the clock signal generated in response to detecting a change in a droopy supply voltage of the adaptive oscillator. The new frequency generated by the adaptive oscillator is based in part on a difference between the droopy supply voltage and a regulated supply voltage of the adaptive oscillator.
