Come on, Zulfi!Hi,
Kindly guide me
Rich (BB code):How many full and half adders are required to add 16 bit numbers?
Kindly guide me with this question.
Zulfi.
How many half/full adders are require to add 1 bit numbers?Half Adders take two operand bits and produce outputs: sum and carry out
Full Adders take two operand bits and a carry in and produce outputs: sum and carry out
A full adder adds two 1-bit numbers along with a single 1-bit number (the carry-in) producing a 1-bit sum and a 1-bit carry-out.Hi,
Thanks all for trying to help me with this question.
I know the folllowing definitions and i know their truth tables also but i cant understand the pattern.
How many half/full adders are require to add 1 bit numbers?
H.A=1, F.A=0
How about 2 bit numbers?
I dont know.
How about 3 bit numbers?
F.A=1
Sorry, I cant create the pattern.
Zulfi.
This clears the confusion of Cin and Cout. But even then we have to do internal connections. So I think we would need 3 F.A? Is this correct?The Cin ports are NOT inputs to the 3-bit adder. If you put this into a box and labeled it "Zulfi's 3-bit adder in a box", which wires would you pass into the box for your input and which wires would you bring out of the box for your output? You would only pass in the two 3-bit values A[2:0] and B[2:0] (so six inputs, total) and you would only bring out the three sum bits, sum[2:0] and the carry out of the final stage (which you might call Cout or you might just call it sum[3]), so you would have four outputs.
