Abstract: A processing unit monitors, over a sliding time window, the number of instructions dispatched for execution at the processing unit. In response to the number of instructions exceeding a threshold, the processing unit throttles (e.g., pauses) the dispatch of instructions for a specified amount of time. The processing unit thus ensures that the number of dispatched instructions does not change too rapidly in too short a period of time reducing the likelihood of sudden changes in processing unit current, without unduly impacting the performance of the processing unit across all workloads.
