Fault-tolerant adder design in quantum-dot cellular automata
Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for faster speed, smaller size, and low power consumption than semiconductor transistor based technologies. Previously, adder designs based on conventional designs were examined for implementation with QCA technology. This paper utilizes the QCA characteristics to design a fault-tolerant adder that is more...

متن کاملPractical Fault Tolerant 2D Cellular Automata
Cellular automata often suffer from a level of brittleness that makes them susceptible to even the smallest unexpected environmental changes. We propose a method of converting CAs into more robust structures called meta-CAs that utilize cell redundancy along with added rules to correct errors and reproduce the functionality of the original CA. We show that the use of these meta-CAs can greatly ...
