Abstract:

As the advancements in VLSI industry reach new heights, the feature size will keep getting small. More and more logical units will be integrated on a single piece of silicon following Moore’s law. With increasing number of transistors, power dissipation becomes a critical issue. According to modern studies, power dissipation can be reduced by making use of reversible logic gates over conventional logic gates. This technique finds enormous advantages in low power application like portable devices, cryptography, quantum computing and nanotechnology. Different reversible gates are introduced in this research project. Basic arithmetic and logical operations are realized from level 0. The realized operations are used as basic blocks to design complex special adders. All introduced modules are designed using Verilog on Xilinx ISE V13.2
and ISim simulator.
