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.
