Craving an adventure to wake them from their lethargic Mexican holiday before they return home, four friends set off in search of one of their own who has travelled to the interior to investigate an archaeological dig in the Mayan ruins. And at that moment their world changes for ever.

Designing Asynchronous Circuits using NULL Convention Logic (NCL) begins with an introduction to asynchronous (clockless) logic in general, and then focuses on delay-insensitive asynchronous logic design using the NCL paradigm. The book details design of input-complete and observable dual-rail and quad-rail combinational circuits, and then discusses implementation of sequential circuits, which require datapath feedback. Next, throughput optimization techniques are presented, including pipelining, embedding registration, early completion, and NULL cycle reduction. Subsequently, low-power...
