Control_—mechanism for selectively shorting clock grid by electrically connecting and disconnecting clock branches once per clock cycle

摘要

Systems, methods, and other embodiments are described that are associated with selective shorting of clock branches. In one embodiment, an apparatus includes a selective shorting device connected between a first clock branch that conducts a slow clock signal having a first frequency and a second clock branch that conducts a fast clock signal having a second frequency that is an integer multiple of the first frequency. The selective shorting device is configured to electrically connect and disconnect the first clock branch and the second clock branch. The selective shorting control mechanism is configured to control the selective shorting device to electrically connect the clock branches during a controlling portion of the slow clock signal.

1. An apparatus, comprising:
a selective shorting device connected between a first clock branch that conducts a slow clock signal having a first frequency and a second clock branch that conducts a fast clock signal having a second frequency that is an integer multiple of the first frequency; wherein the selective shorting device is configured to electrically connect and disconnect the first clock branch and the second clock branch; and a selective shorting control mechanism configured to, once per slow clock cycle:
control the selective shorting device to electrically connect the first clock branch to the second clock branch; andcontrol the selective shorting device to electrically disconnect the first clock branch from the second clock branch.
