Abstract
A processor adjusts frequencies of one or more clock signals in response to a voltage droop at the processor. The processor generates at least one clock signal by generating a plurality of base clock signals, each of the base clock signals having a common frequency but a different phase. The processor also generates a plurality of enable signals, wherein each enable signal governs whether a corresponding one of the base clock signals is used to generate the clock signal. The enable signals therefore determine the frequency of the clock signal. In response to detecting a voltage droop, the processor adjusts the enable signals used to generate the clock signal, thereby reducing the frequency of the clock signal droop.
