Abstract

For example, a power-setting controller may be configured to provide a power setting for a processor based on one or more sensor-based inputs corresponding to one or more temperature sensors. For example, a sensor-based input corresponding to a temperature sensor may include a temperature input and a target temperature. For example, the power-setting controller may include one or more NNPID-based power controllers configured to provide one or more sensor-based power settings corresponding to the one or more temperature sensors. For example, an NNPID-based power controller of the NNPID-based power controllers may be configured to provide a sensor-based power setting corresponding to the temperature sensor based on the sensor-based input corresponding to the temperature sensor. For example, the NNPID-based power controller may include an NNPID controller configured to determine a temperature setting based on the temperature input and the target temperature corresponding to the temperature sensor.
