Designing of Full Subtractor using Half-SubtractorsA Full-Subtractor can also be implemented using two half-subtractors and one OR gate. The circuit diagram for this can be drawn as,The Boolean expressions for Difference and Borrow are,
Half adder and half subtractor are at the core of all arithmetic operations; these optical circuits add or subtract two input bits at a time to produce sum and carry or difference and borrow as outputs, respectively. In this work, Half adder/subtractor design based on the electro-optic ...
The proposed gate is used to design efficient adder and subtractor units. The proposed gate can be used to implement AND, XOR, XNOR and NOT gates. It is demonstrated that the adder/subtractor architectures designed using the proposed gate are much better and optimized, in terms of reversible ...
Full Adder using Half Adder A Full Adder can also be implemented using two half adders and one OR gate. The circuit diagram for this can be drawn as, And, it could be represented in block diagram as, The Boolean expression for Sum and Carry is as, ...
This example describes a two-input, 8 bit adder/subtractor design in Verilog HDL. The design unit dynamically switches between add and subtract operations with anadd_subinput port. Figure 1. Adder/Subtractor top-level diagram. Download the files used in this example: ...

A half adder adds two bits and produces a sum and a carry output. A full adder adds three bits, two input bits, and a carry bit, and produces a sum and a carry output. Similarly, a half subtractor subtracts two bits and produces a difference and a borrow output. A full subtractor ...

In this paper, four plasmonic combinational logic functions have been proposed, designed and simulated using 2-D FEM. These combinational logic functions are half-adder, half-subtractor, comparator one-bit, and full-adder. The combinational logic functions are constructed by Nano-rings IMI plasmonic...
Prelab: 1.Design a4-bit adder/subtractor using only full adders and Exclusive-OR gates. Do not use any multiplexers. 2.Design a combinational circuit using a minimum number of Full adders, and logic gates which will perform A plus ...
