Dual banyan network (DBN) design: A quantum-dot cellular automata (QCA) based approach

The inputs use a non-blocking internal process to distribute the data using address of the port of the receiver using a non-blocking interior multistage transmission architecture known as a dual banyan network (DBN). The DBN is a primary component in many communication and switching applications because it efficiently routes and switches data packets. This study shows how to construct a single-layer DBN using QCA. A single layer 2 × 2 crossbar network (CBN) with two inputs and two outputs is suggested and developed in QCA to create the proposed communication architecture. In this study, a 2 × 2 CBN is used as a preliminary building block to create a 4 × 4 DBN. We present a detailed analysis of the DBN design, including its architecture, functionality, and performance evaluation. For a fault-free crossbar switch design, the consequence of a fault that affects the control line is noticed and surpassed. Similarly, the proposed architectures' fault tolerance has been described by considering fault scenarios at the 2 × 2 CBN control lines. Considering the logic gates, number of clock cycles, and device size complexity of the designs are measured. All of the designs were implemented using QCADesigner software. The power dissipation of the suggested layouts.
