Dynamic Adaptive Voltage-Frequency Guardband Control Circuit

摘要

In certain aspects, the system includes a voltage-drug mitigation circuit configured to monitor voltage droop at a supply voltage supplied to the circuit and to perform voltage-drug mitigation for the circuit if the monitored voltage droop is above the droop threshold. . In one aspect, the system also includes a performance monitor configured to track the number of clock cycles for which the voltage-drug mitigation circuit performs voltage-drug mitigation within a time duration and adjust the droop threshold based on the number of clock cycles. do. In another aspect, the system also tracks the number of times that the voltage-loop mitigation circuit performs voltage-drug mitigation within a time duration, and based on the number of times the voltage-loop mitigation circuit performs voltage-drug mitigation within a time duration. A performance monitor configured to adjust the droop threshold.
