Abstract
In any wide-range processing system, rapid interconnecting networks are employed between the processing modules and embedded systems. This study deals with the optimized design and implementation of Switching Element (SE) which operates in four modes, accepting two inputs and delivering two outputs. The Shuffle-Exchange Network (SEN) can be used as a single-stage as well as a multi-stage network. SEN is used as an interconnection architecture which is implemented with exclusive input-output paths with simple design. The SE acts as a building block to the Multi-stage Shuffle-Exchange Network (M-SEN) with facilities to perform unicast and multicast operation on the inputs. An 8x8 M-SEN model is also implemented, which works in three modes of communication, termed as "One-to-One", "One-to-Many" and "One-to-All" M-SEN configuration. All the QCA circuits have been implemented and simulated using CAD tool QCADesigner. The proposed QCA-based M-SEN design is better in terms of area occupied by 14.63%, average energy dissipation by 22.75% and cell count with a reduction of 84 cells when compared to reference M-SEN architecture. The optimization of the design in terms of cell count and area results in lesser energy dissipation and hence can be used in future-generation complex networks and communication systems.
