Daniel W. Knox has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for deterministic communication across clock domains
    Patent number: 7111184
    Abstract: A clock distribution and control system (10) includes one counter (30) in a clock generation domain and another counter (40) in a phase-delayed clock domain. The phase-delayed domain counter (40) output is combined with a programmable offset value chosen based on the phase delay of the clock distribution system. The result is used to insure that communication between logic in the clock generation clock domain and logic in the phase-delayed clock domain occurs deterministically on the correct clock edge for a range of clock frequencies.
