Design and Implementation 16 BIT REVERSIBLE LOGIC ALU with 15-Operations

Abstract

Reversible logic is one of the emerging technologies having promising applications in quantum computing. This project will deal with the design of a 16 bit reversible Arithmetic Logic Unit (ALU) with 15 operations is presented by making use of Double Peres gate, Fredkin gate, Toffolli gate, DKG gate and NOT gate. A new VLSI architecture for ALU using reversible logic gates is proposed. ALU is one of the most important components of CPU that can be part of a programmable reversible computing device such as a quantum computer. A first single bit reversible ALU and second single bit ALU are designed and Then 16 single bit ALU’s are cascaded together taking carry out of ALU performing LSB operation as an input to carry in of ALU performing next LSB operation. Design is implemented and verified in Verilog in modelsim Altera 6.6d.
