A novel design of nano router with high-speed crossbar scheduler for digital systems in QCA paradigm

Abstract

Purpose The nano-router would be a mastery device for providing high-speed data delivery. Here nano-router with a space-efficient crossbar scheduler is used for making absolutely less consumption in power. Design/methodology/approach In the emerging modern technology, every one of us is expecting a delivery of data at a high speed. To achieve high-speed delivery the authors are using the router. The router used here is at nanoscale reading which provides a compact size. Findings This can be implemented using the modern tools called Quantum-dot Cellular Automata (QCA) which is operated without the use of a transistor. As conventional complementary metal oxide semiconductor (CMOS) designs have some limitations such as low density, high power consumption and requirement of a large area. Research limitations/implications To overcome these limitations the QCA is used. It characterizes capability is used to substituting CMOS technology. The round-robin fashion is used in a high-speed space-efficient crossbar scheduler. Practical implications The simulation of the planned circuit with notional information established the practical identity of the scheme. Social implications The proposed nano router can be stimulated in the QCA environment using the QCADesigner tool and the power of the router can be calculated with the QCADesigner–E tool. Originality/value The proposed nano router can be stimulated in the QCA environment using the QCADesigner tool and the power of the router can be calculated with the QCADesigner–E tool. In this work, the performance of the router can be done in both the QCA environment and CMOS technology.

Efficient Nano-Scale Design of TIEO Based Reversible Logic Toffoli Gate Priority Encoder in Quantum-Dot Cellular Automata

“…There are several QCA implementations of the Toffoli gate. The Toffoli gate concept was implemented in [19] using four large-area majority gates. The architecture makes use of four MGs, one of which performs the role of an OR gate in addition to the three AND gates.…”

“…The Toffoli gate has numerous QCA implementations. Work [19] used four majority gates with a sizable area to accomplish the Toffoli gate design. The design employs four MGs, with the fourth acting as an OR gate and the other three as AND gates.…”

“…As shown in Fig.5, the circuit is divided into four clock zones, each of which has the "Switch," "Hold," "Release," and "Relax" phases. Signal propagation across QCA wire, which is made up of a series of QCA cells, is comparable to that through a traditional shift register[19].Fig 5 Shows the various zones and phases in QCA clocking.…”
