Abstract
Various embodiments of a clock generator are disclosed. An example system may include a functional unit, and a clock generation unit configured to adjust a frequency of an output clock signal responsive to an assertion of an enable signal from the functional unit. The clock generation unit may also be configured to halt the output clock signal responsive to a de-assertion of the enable signal by the functional unit and to restart the output clock signal responsive to a determination that a first predetermined amount of time has elapsed since the output clock signal was halted. The clock generation unit may be further configured to adjust the frequency of the output clock signal responsive to restarting the output clock signal, and to halt the output clock signal responsive to a determination that the frequency of the output clock signal is within a predetermined frequency range that includes the target frequency.
