A multistage and internally non-blocking communication architecture called a dual banyan network distributes the inputs based on the receiver’s port address with an internally non-blocking technique. It interprets the port address or output address as a string. The creation of a singlelayer dual banyan network utilizing QCA is demonstrated in this work. This study achieves a 4× 4 dual banyan network using a crossbar switch as a key-building piece. Device area, latency, and logic gates are taken into consideration when judging the designs. To ensure design accuracy, theoretical parameters, and simulation data have been compared. Using the QCADesigner tool, all the designs are put into practice.
