Cellular Automata with an Infinite Number of Subshift Attractors
The concept of an attractor is essential for understanding the dynamics of cellular automata. An attractor is defined as a limit set (intersection of forward images) of a nonempty clopen (closed and open) invariant set. Classification of cellular automata based on the system of their attractors has been considered in Hurley [1] or Kůrka [2]. The basic distinction is between cellular automata wh...
متن کاملCellular Automata: Elementary Cellular Automata
Cellular automata (CA) are discrete dynamical systems consist of a regular finite grid of cell; each cell encapsulating an equal portion of the state, and arranged spatially in a regular fashion to form an n-dimensional lattice. A cellular automata is like computers, data represented by initial configurations which is processed by time evolution to produce output. This paper is an empirical stu...
متن کاملFault-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 کاملExploring and Exploiting Quantum-Dot Cellular Automata
The Full Adders (FAs) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. With respect to the MOSFET restrictions, its replacement by new devices and technologies is inevitable. QCA is one of the accomplishments in nanotechnology nominated as the candidate for MOSFET replacement. In this article 4 new layouts are presente...
