Abstract: An electronic device includes an accelerated processing unit (APU) and multiple elements. The APU performs operations for a platform boost and throttle (PBT) controller. For the operations, the APU receives a platform electrical power limit, the platform electrical power limit being a limit on a total electrical power allowed to be consumed by a group of the elements at a given time. The APU then determines a present platform electrical power consumption. The APU next adjusts one or more operating parameters for specified elements from among the group of elements to control electrical power consumption by the specified elements based on a relationship between the present platform electrical power consumption and the platform electrical power limit.
