Goal
- First step into logic
Level
- Knowing how to use a breadboard
Component
- Only one logic gate array.
How to
The logic circuit is as followed :
From this chip, we would like to make a adder. It is one of the basic component of everyCPU. It's use is to have two bits. They represent a state either 1 or 0. We will add them with the following scheme : 1 + 1 = 10 1 + 0 = 01 0 + 1 = 01 0 + 0 = 00 ^ this bit is the first bit we add, we will call it A later on.
^ this bit is the second bit we add, we will call it B later on.
^ this bit is the most significant bit. We call it C1 later on.
^ this bit is the least significant bit. We call it C0 later on.
Just follow the
