Implementation of reversible gates in FPGA structure
Marek Pawłowski, Zbigniew Szymanski · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2017
The paper presents reversible circuits modelling methods in the FPGA structures. Three different methods of reconfigurable reversible gate descriptions are proposed - a direct method of output calculation and two methods of composing the gate from Fredkin and Toffoli gates. The paper shows both 4-bit and 8-bit gates. Application of developed test bench verified the correctness of our designs. The presented descriptions can be used for modelling of complex elements used e.g. in cipher machines based on quantum algorithms.
