This page of verilog sourcecode covers HDL code for half adder,half substractor,full substractor using verilog.
A single full-adder has two one-bit inputs, a carry-in input, a sum output, and a carry-out output. Many of them can be used together to create aripple carry adderwhich can be used to add large numbers together. A single full-adder is shown in the picture below. 1-bit Full-Add...

There are two examples for each VHDL and Verilog shown below. The first contains a simple carry lookahead adder made up of four full adders (it can add together any four-bit inputs). The second example uses agenericthat creates a carry look ahead adder that accepts as an input parameter ...
In this way it is possible in this case to assign the result of the adder to two bit vector. Notice how the vector array is formed using the curly bracket {cout,A}. The rightmost part of the vector {cout,A} , which is A in this case forms the LSB. ...
NEW DESIGN METHODOLOGIES FOR HIGH-SPEED MIXED-MODE CMOS FULL ADDER CIRCUITS This paper presents the design of high-speed full adder circuits using a new CMOS mixed mode logicfamily. The objective of this work is to present a new fu... S Wairya,RK Nagaria,S Tiwari - 《International Journal...
Show the result of running Shellsort on the input 9, 8, 7, 6, 5, 4, 3, 2, 1 using the increments 1, 3, 7 . Encode -34 into an 8 bit 1's complement binary integer. True or false: A half adder is normally used when a carry input may be applied. ...
The Reduced complexity reduction method smartly reduces the number of half adders with 70-80% reduction in an area of half adders than standard Wallace multipliers. 展开 关键词: Energy Efficient full adders CMOS full adder Wallace Multiplier High speed multiplier ...
Generally, the full subtractor is one of the most used andessential combinational logic circuits. It is a basic electronic device, used to perform subtraction of two binary numbers. In the earlier article, already we have given the basic theory ofhalf adder & a full adderwhich uses the binary...
Half adder logic diagram Full size image On the other hand, the full adder adds three logical variables and provides two outputs, sum and carry. If the input variables are A, B, and Cin, the two outputs can be found using Eq. 5. $$\begin{aligned} & {\text{Sum}} = \left( {\te...
