Adders are one of the widely used digital components in digital integrated circuit design. In this paper, various adder structures can be used to execute addition such as serial and parallel ...

Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of ...

[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 ...
