Abstract
Aspects relate to limits management for a processor power distribution network. In an aspect, an electronic device has a processor with a processing core that is coupled to a power rail. The power rail is external to the processor. A current sensor is associated with the output of the power rail and configured to produce current sensor readings. A state-space unit is coupled to the current sensor. The state-space unit has a predictive model to apply the current sensor readings to the predictive model to predict a current budget for the processing core. A limit manager is configured to generate a current limit in response to the current budget. The limit manager limits a current draw of the processing core in response to the current limit.
