I need to Modify my Full Adder implementation to conduct addition of two 4-bit binary numbers. The new implementation should give the summation of two numbers and any overflow carry out. How can I achieve this???

Can I use two Full Adders (one 4-bit binary numbers as input for each Full Adder) ????

If you search Digikey for older full adders TTL and CD4xxx series, you can find block diagrams.
