DYNAMICALLY ADAPTIVE VOLTAGE-FREQUENCY GUARDBAND CONTROL CIRCUIT

In certain aspects, a system comprises a voltage-droop mitigation circuit configured to monitor voltage droop in a supply voltage supplied to a circuit, and to perform voltage-droop mitigation for the circuit if the monitored voltage droop is equal to or greater than a droop threshold. In one aspect...

Summary:In certain aspects, a system comprises a voltage-droop mitigation circuit configured to monitor voltage droop in a supply voltage supplied to a circuit, and to perform voltage-droop mitigation for the circuit if the monitored voltage droop is equal to or greater than a droop threshold. In one aspect, the system also includes a performance monitor configured to track a number of clock cycles over which the voltage-droop mitigation circuit performs the voltage-droop mitigation within a time duration, and to adjust the droop threshold based on the number of clock cycles. In another aspect, the system also includes a performance monitor configured to track a number of times that the voltage-droop mitigation circuit performs the voltage-droop mitigation within a time duration, and to adjust the droop threshold based on the number of times that the voltage-droop mitigation circuit performs the voltage-droop mitigation within the time duration.
