input A0 A1 B0 B1 Cin

output Sum0 Sum1 Cout....

Thx a lot
 

You mean 2 bit full adder !!!
well attached is a powerpoint p;ease check it if you need help be more precise:

full adder input: A,B,C output S and Cout


Cout= AB + CB + AC

S = (A' B + A B') XOR C
= (A XOR B) XOR C

O...sorry

How about 2- bit full adder??

I can nit find in the powerpoint attached file

Because I found that the S0 S1 and carry is very complex

I found S0 is similar to 1 bit full adder....I also is A0 XOR B0 XOR Cin
but S1 is very complex

Any one can help....thank
 

THANKS PAKITOS, excellent post :D.

usually when they say full adder, we add three numbers, each number of 1 bit.

the ppt that pakitos posted is graphical and EXCELLENT + contains correct and easy equations.


cyw1984 you mean that you know the S0 but you want us to post the S1, right ?

and why u said : O...sorry ??
