An Asynchrobatic, radix-four, carry look-ahead adder

Using Positive Feedback Adiabatic Logic to implement Reversible Toffoli Gates

“…However, this was based upon Reversible Energy Recovery Logic (RERL) [14], and as such, requires six-or eight-phase clocking. The proposed style in this paper utilizes only four-phase clocking, which makes the energy recovery structures easier to implement, and can also means such systems could be viably implemented using Asynchrobatic logic [15] [16] techniques.…”

A system for calculating the Greatest Common Denominator implemented using Asynchrobatic Logic

“…It is based upon the adder detailed in these authors' previous work [2]. The adder detailed in that paper has been converted into a selectable subtractor or reverse subtractor by the inclusion of an input pre-processing stage.…”

“…These authors' previous works have shown that it is possible to implement both simple and more complex data-path structures using this design methodology [1] [2]. This work provides a brief explanation of the Asynchrobatic logic style, an explanation Euclid's method, and then provides details of the implementation and testing of the complete system.…”
