Abstract
In some embodiments, a processor core includes an energy tracking circuit and an execution management circuit. The energy tracking circuit is configured to determine an amount of remaining allocated energy of the processor core. The execution management circuit is configured to make a determination whether to stall execution of one or more pipeline operations at the processor core based on a comparison of the amount of remaining allocated energy to a stall threshold. The determination involves applying one or more pseudo-random components to the amount of remaining allocated energy, the stall threshold, or both. The determination is made such that the smaller the amount of remaining allocated energy, the more likely the execution of one or more instructions is to be stalled.
