Abstract
A design is presented for the implementation of an event driven asynchronous buffering mechanism which functions within a delay-insensitive two-phase handshake environment and performs in a manner similar to that of a synchronous 'tri-state' driver element.
The design is derived from a series of currently available asynchronous logic elements that perform latching functions from within either a two-phase or a four-phase operational medium. A solution to the problem of the correct generation of completion signals from within such a two-phase functionality is presented.
The final buffer design is verified using both a Petri Net and Signal Transition Graph analysis with the resultant circuit realisation being simulated using the WARP VHDL Development System.
