Connect the 3 selection pins on both multiplexers in parallel to the A, B, and Carry inputs.
Use the output of one multiplexer as the Sum output and connect its 8 inputs according to the truth table for the Sum function.
Use the output of the other multiplexer as the Carry output and connect its 8 inputs according to the truth table for the Carry function.
Connect any enables, etc. on both multiplexers so that they are always enabled and passing signal.

How do you perform Parallel Adder Addition?
A binary parallel adder is a digital function that produces arithmetic sum of two binary numbers in parallel. It consists of full-adder combinational arrangement thus, the output carry from one full adder connected to the input carry of next full- adder.
How to draw the logic circuit for full adder using half adder?
asdfghjkl;' s-sum and c'-carry see for half adder s=a(xor)b and c'=ab for full adder s=a(xor)b(xor)c and c=ab+bc+ac or ab+c(a(xor)b) we can convert two half adder to full adder with help of and or gate. . . ! we got two half adder * for first half adder input is a and b therefore. . .s=a(xor)b and c'=ab * for second half adder input is a(xor)b and c therefore. . .s=a(xor)b(xor)c and c' is (a(xor)b)c note: now connect the c' of first half adder and second half adder to 'or' gate resulting is ab+c(a(xor)b)
What are the advantages of half and full adder circuit?
Do you mean :- how to get full adders by using half-adders? For this question refer following answer - A full-adder can be obtained by combining two half-adders and one or gate. Details on full-adder and half-adder can be referenced from following link http://www.fullchipdesign.com/fulladder.htm
Why we use half adder even when full adder is more usefull?
A half adder has less components, and may therefore be cheaper. So, in cases where all you need is a half adder, it may be more convenient to use a half adder. Or it may be more convenient to mass-produce only the full adders, since a full adder can work as a half-adder as well.Also, in introductory electronics textbooks, the half-adder would be introduced first, just because it is simpler.

How a Full Adder with the help of two Half Adders?
Connect two half Adders with an OR gate to make a Full Adder.
Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
Advantages of full adder?
A full adder is a logical unit. The full adder must obey truth tables. They are simple, but are not speedy.
Presentation on half adder and full adder?

Application of full adder?
full adder reduces circuit complexibility
Can full adder become half adder?
No. A full adder is two half adders with a carry circuit to combine the two carries together.

What is the basic differences between full adder and half adder?
Number of input bits. Half adder: (Cout,Q) := A+B Full adder: (Cout,Q) := A+B+Cin
Define half adder and full adder?
From wikipedia: A half adder is a logical circuit that performs an addition operation on two binary digits. The half adder produces a sum and a carry value which are both binary digits. A full adder is a logical circuit that performs an addition operation on three binary digits. The full adder produces a sum and carry value, which are both binary digits. It can be combined with other full adders or work on its own.
