Abstract
The quantum-dot cellular automata (QCA) technology is considered as a possible nanoelectronic technology for future computing facilities. The leading role of QCA wires makes it preferable for serial data transfer/processing. Many modern computer applications require direct processing of decimal information without representation and conversion errors. The main purpose of the research is to design a novel QCA serial decimal digit multiplier. A QCA wire can be considered as a virtual tape with written binary symbols. The designed multiplier uses the Turing machine run-time multiple tapes reconfiguration to multiply two decimal digits encoded in the 5-bit Johnson–Mobius code. The proposed multiplier has successfully passed verification. In comparison with possible QCA BCD multipliers, it shows significant hardware simplification.
期刊介绍：
he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered.
In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
