Abstract
In some implementations, a system includes a universal adaptive voltage scaling monitor (UAVSM) and an adaptive voltage scaling (AVS) controller. The UAVSM is configured to delay a first signal generated by a signal path by an adjustable time period, compare the delayed first signal and a second signal associated with the signal path, and provide an error signal indicating a result of the comparison, where the error signal is asserted when the result of the comparison indicates that the delayed first signal is different from the second signal. The AVS controller is configured to provide a first control signal indicating that the voltage is to be increased when the received error signal is an asserted error signal, and provide a second control signal indicating that the voltage is to be decreased when the received error signal is an unasserted error signal and the signal path is active.
