Abstract: The low end operating voltage of an integrated circuit is adjusted. Oscillations are counted at a ring oscillator on the integrated circuit over a designated period of clock cycles. Based on the number of oscillations, a prediction model associated with a first set of device degradation data and a second set of static random-access memory (SRAM) low end operating voltage data is used to select a low end operating voltage limit for a processor on the integrated circuit. The low end operating voltage of the processor is set based on the selected low end operating voltage limit. These steps are repeated multiple times during operation of the processor. A method of testing integrated circuits to provide the data employed to produce the prediction model is also provided.

Abstract: An apparatus and method for dynamically adjusting power limits for processing nodes and other components, such as peripheral interfaces, is disclosed. The apparatus includes multiple processing nodes and other components, and further includes a power management unit configured to set a first frequency limit for at least one of the processing nodes responsive to receiving an indication of a first detected temperature greater than a first temperature threshold. Initial power limits are set below guard-band power limits for components that do not have reliable reporting of power consumption or for cost or power saving reasons. The amount of throttling of processing nodes is used to adjust the power limits for the processing nodes and these components.

Abstract: A system has a plurality of electronic components including a memory, a PHY coupled to the memory, and one or more other electronic components. Power consumed by the PHY is estimated during operation of the system. Estimating the power consumed by the PHY includes modeling the power consumed by the PHY as a linear function with respect to memory bandwidth. Available power for the PHY is determined based at least in part on the estimated power consumed by the PHY. At least a portion of the available power for the PHY is allocated to at least one of the one or more other components.

Abstract: Systems, apparatuses, and methods for managing power usage of integrated circuits. One or more processor cores may be powered down when the system is idle. Even if there is no user activity, the processor core(s) may be woken up periodically for background downloads to retrieve the latest status for social media and other applications. Additionally, a power management unit may track the average number of active cores and the average core utilization. If the average number of active cores is less than a first threshold and the average core utilization is less than a second threshold, the power management unit may generate a request to offline one or more cores. Still further, when the processor's skin temperature is above a threshold and all of the cores are operating at the lowest acceptable operating point, one or more cores may be powered down.

Abstract: A power management module of a processor places a compute unit in a low power mode (e.g., an idle mode) in response to identifying that the compute unit is expected to experience little to no processing activity for a threshold amount of time. In response to receiving an indication from a message controller that a message is targeted to the compute unit, the power management module selects a different compute unit that is presently in an active power mode and provides the message to the selected compute unit for processing. The compute unit can be selected based on any of a variety of criteria, such as the compute unit being in a stall condition, an indication from a performance monitor that the compute unit is executing a relatively inefficient program thread, and the like.
