Abstract
A power regulator provides current to a processing unit. A clock distribution network provides a clock signal to the processing unit. A level-based droop detector monitors a voltage of the current provided to the processing unit and provides a droop detection signal to the clock distribution network in response to the voltage falling below a first threshold voltage. The clock distribution network decreases a frequency of a clock signal provided to the processing unit in response to receiving the droop detection signal. The level-based droop detector interrupts the droop detection signal that is provided to the clock distribution network in response to the voltage rising above a second threshold voltage. The clock distribution network increases the frequency of the clock signal provided to the processing unit in response to interruption of the droop detection signal.
