Abstract: Power monitoring and limiting of processing units in a processor-based system to limit the overall power consumption of the processor-based system. In exemplary aspects, to limit the overall power consumption of the processor-based system while attempting to achieve an optimized performance of all the processing units, an overall power limit budget is allocated for the processing units (“processing unit power limit budget”). The processor-based system is configured to dynamically determine a total processing unit power limit budget available for the processing units based on remaining overall power available not consumed by other power consuming circuits. The processor-based system is configured to allocate the total processing unit power limit budget for processing units, that is then allocated to the different processing units based on their variances in workloads to try to achieve an optimal performance of the processing units while keeping the processor-based system within its overall power consumption limit.
