Executive Summary

This paper presents a simple Multiplexer based Field programmable gate arrays with interconnects based on quantum cellular automata technology. Quantum Cellular Automata (QCA) technology is a promising nanotechnology of the future. QCA based 4:1 Multiplexer are designed and constructed as a module in a FPGA. Multiplexer based designs are used to implement complex Boolean functions and each module can act as a logic element or simple Multiplexer. The authors have studied here, NOR based logic to implement Sum function of an adder in a QCA FPGA. Finally, they have designed and simulated the MUX based logic elements to construct QCA FPGA. This paper can be useful for building complex Configurable logic blocks to design a complete FPGA.
