I've built this because I was tired of using just full adders in subtraction and having a bad result when it is supposed to be negative. The signs should explain everything.
FEATURES:
- Expandable : Just copy the modules, and you can easily have a 32-bit adder... or bigger...
- Supports negative numbers : if your inputs are -bit, the answer ranges from 2n+1 - 2 to -(2n -1). This means that in case of a 5-bit input, answers will range from 62 to -31.
- Easy to reproduce: Uses half adders and full adders + an easy subtraction carry system.
