Abstract: Various embodiments include power management system methods including receiving, at a processor(s), a notification signal triggering the processor(s) to implement power usage mitigation at the processor(s), determining, by the processor(s), a mitigation amount of power rail power by which to mitigate current usage at a power rail based on a use case for the power rail, and implementing power usage mitigation at the processor(s) by the processor(s) sufficient to mitigate power usage at the power rail by the mitigation amount of power rail power. Power usage mitigation may include reducing processor(s) current usage: by a predefined amount; proportional to the amount a power rail current exceeds a power rail current threshold; by the amount of current exceeding a processor current threshold; or by a smallest amount between the amount a power rail current exceeds a power rail current threshold and the processor(s) current exceeds a processor current threshold.

Abstract: Various embodiments include a shared power rail monitoring circuit included in integrated circuits configured to manage worst case power on a shared power rail within the integrated circuit. Various embodiments include circuit components configured to determine allocated currents for each processing block or subsystem core on the shared power rail based on operating parameters of each processing block or subsystem core, and set a mitigation level for one or more processing blocks or subsystem cores on the shared power rail based at least in part on the determined allocated currents for each processing block or subsystem core on the shared power rail. The operating parameters may be voltage or voltage mode, temperature and operating frequency of each processing block or subsystem core.

Abstract: A method for device cooling includes determining whether an amount of power allocated to devices drawing power from a shared power rail exceeds a power rail limit. The method also includes reducing device traffic to a specified bandwidth level for at least one of the devices in response to the amount of power allocated to the devices drawing power from the shared power rail exceeding the power rail limit.

Abstract: A system for performing peak current mitigation in an application programming subsystem (APSS) dynamically performs mitigation based at least in part on power rail voltage and leakage current obtained at boot time. The voltage and leakage current obtained at boot time are used to estimate peak current. A map that is generated prior to boot time maps estimated peak current to throttling level and dictates different levels of throttling to be performed for different ranges of estimated peak current. At boot time, the map is used to map the estimated peak current to a level of throttling to be applied. If conditions at run time indicate that peak current is occurring or is likely to occur soon, the mapped level of throttling is applied to mitigate the peak current.

Abstract: A method for power control includes receiving first power consumption data of a first compute device based on measurements of the first compute device, and receiving second power consumption data of a second compute device based on measurements of the second compute device. The method further includes receiving system power data to obtain a system power limitation. The method also includes calculating a power budget threshold for the first compute device and the second compute device based on the first power consumption data, the second power consumption data, and the system power limitation. The method includes controlling performance of the first compute device to operate within the power budget threshold, and controlling performance of the second compute device to operate within the power budget threshold.
