  • Abstract:
  • Modern computing architectures are evolving toward systems where computational reversibility plays a fundamental role. A key innovation in this domain is the development of a novel arithmetic logic unit (ALU) that maintains complete bidirectional operation capabilities. This advanced ALU architecture employs sophisticated multiplexer configurations and precise control signaling to achieve reversible computation. As a critical component within the central processing unit, this reversible ALU design represents a significant step toward programmable quantum computing systems. The architecture leverages multiplexer-based operation selection, enabling flexible computational pathways while maintaining information preservation. Through implementation of programmable reversible logic gates, this design transcends traditional AND/OR gate limitations. The proposed 4-bit ALU configuration demonstrates enhanced efficiency by utilizing inverted data references, significantly reducing power consumption in logic circuits. The implementation, validated through comprehensive simulation using industry-standard tools including Verilog HDL, ModelSim Altera, and Quartus Prime, confirms the design's viability for next-generation computing applications. This innovative approach represents a crucial advancement in developing energy-efficient, quantum-compatible processing units.
