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.

Abstract: A computer-readable storage medium for controlling voltage droop storing instructions that, when executed by a processor, cause a device to perform operations including receiving a first voltage to a first input of a first component of a device. The first voltage corresponding to a first logical value causes a first internal power supply of the first component to be charged using an external power supply. The operations further include providing a second voltage to a second input of a second component of the device in response to a first voltage level of the first internal power supply satisfying a second voltage level. The second voltage corresponding to the first logical value causes a second internal power supply of the second component of the device to be charged using the external power supply.

Abstract: Voltage droop control is disclosed. A device includes a first component coupled to an external power supply and a second component coupled to the external power supply. The first component includes a first input configured to receive a first voltage, a first internal power supply configured to be charged by the external power supply in response to the first voltage corresponding to a first logical value, and a voltage droop controller configured to output a second voltage via a first output. The second voltage corresponds to the first logical value in response to a first voltage level of the first internal power supply satisfying a second voltage level. The second component includes a second input configured to receive the second voltage from the first output.
