Making An 8 bit adder out of two 4 bit adders

Does it have an "Overflow" output? I think that would be the same as "Carry Out," though it has been a few years since my cpu design class.

Create A Full Adder Using The C Preprocessor

[Phillip] wanted to play with the C preprocessor. He decided to do that by creating a 4 bit full adder. We know this is pretty useless in everyday life, but it was a great learning experience. The ...

Creating A Full Adder Circuit Using NAND Gates

How do you create a full adder using nand gates? A Full-adder circuit adds three one-bit binary numbers (A, B, Cin) and outputs two one-bit binary numbers, a Sum (S) and a carry (Cout). It is usually ...
