Engineering Creating a 4 bit full adder logic circuit

[IdontGetIt!]

Hello, i had a quick question, basically i am trying to build a 4 bit full adder logic circuit on a motherboard.
i been trying to research but i came up empty...i would like to know what are the exact parts that i need to successfully build this logic circuit?

thanks..

You can build it using
1- Combination of AND,OR and NOT gates
2- NAND or NOR
2- Decoder and 4 OR gate
3- Multiplexers

Well, if you just need a 4-bit adder, an IC 74LS83 (an IC with one 4-bit adder in it) would suffice.

If you actually want to explore the operation of this adder and build one yourself, then you should look up how a full adder is made. Cascading four full adders would give you a 4-bit adder.

Wikipedia has a well good page on this - http://en.wikipedia.org/wiki/Full_adder#Full_adder
