Asynchronous circuit design

Using null convention logic (NCL) from Theseus (St. Paul, MN), high-performance asynchronous circuits can be designed without any detailed timing analysis to test functionality. With this technology, Sanders and Theseus have started work on a $2.3 million program, funded by Lockheed and DARPA, to develop an NCL-based digital-signal processor for the F-22 aircraft. This comprehensive site describes NCL and shows how it can be used to build asynchronous circuits.
