Abstract: Systems and methods relate to controlling voltage deviations in processing systems. A scheduler receives transactions and to be issued for execution in a pipeline. A voltage deviation that will occur if a particular transaction is executed in the pipeline is estimated before the transaction is issued. Threshold comparators are used to determine if the estimated voltage deviation will exceed specified thresholds to cause voltage overshoots or undershoots. The scheduler is configured to implement one or more corrective measures, such as increasing or decreasing energy in the pipeline, to mitigate possible voltage overshoots or undershoots, before the transaction is issued to be executed in the pipeline.
