Abstract: Growth of research in the field of effective digital computing systems leads to the need of efficient digital design approaches. Reversible logic concept is the result of this necessity. This design approach creates low power efficient digital circuits with improved performance. In the CPU/ALU bus provides the path for data flow and covers major area of the CPU. As the conventional buses are irreversible in nature when data flows through these buses it consumes power and additional hardware is required to sink the generated heat. Moreover by designing a bus using reversible technology power requirement is decreased with the removal of need of heat sink. In this study, we focus upon the designing of common bus structure using reversible logic approach. Common bus structure provides an effective way to provide the facility of communication between computer subsystems. The proposed approach for reversible realization of common bus system is simulated and synthesized for ModelSim simulator and Xilinx Software, respectively.
