Abstract: A scheme is provided for a processor to measure or estimate the dynamic capacitance (Cdyn) associated with an executing application and take a proportional throttling action. Proportional throttling has significantly less impact on performance and hence presents an opportunity to get back the lost bins and proportionally clip power if it exceeds a specification threshold. The ability to infer a magnitude of power excursion of a power virus event (and hence, the real Cdyn) above a set power threshold limit enables the processor to proportionally adjust the processor operating frequency to bring it back under the limit. With this scheme, the processor distinguishes a small power excursion versus a large one and reacts proportionally, yielding better performance.

In addition, a self-monitoring method to be applied to a self-monitoring system is disclosed.

Abstract: A dynamic peak power management system may prevent brownouts while improving performance and user experience compared to conventional techniques. A current threshold may be set below the maximum current capability (Imax) of a battery. If the current drawn from the battery exceeds the current threshold repeatedly, then system components may be throttled to decrease their peak power usage. If the current drawn from the battery stays below the current threshold for some time, then system components may be unthrottled to improve performance. This dynamic adaptable technique for managing peak power does not unnecessarily sacrifice performance by preemptively throttling system components to avoid the rare worst-case scenario where power spikes of system components perfectly align in time.
