Post a save of this real quick :o, i always wondered how parts work on the small scale, so i want to take this apart and learn from it, if you dont mind ^.^

Posting one right now. Just need to extract it from my "main redstone world".

Nice ALU, are you planing to expand on it?
Edit: doesn't it have add?

Thanks. I thought of adding add, but than it would be like 1.5 times bigger and the output would need to be 2 bits which i don't like(lol). These basic functions are enough for a small-scale computer/dedicated machine.

This would just be an "LU" or "Logic Unit" since it doesn't do any Arithmetic.

I assume that you are using XOR gates to do conditional inversion on the inputs and outputs, yes?

I would strongly advise you to try making a multi-bit version of this, since it is very useful to see the large-scale interaction of control-lines with data, and you can observe more interesting data manipulations with larger bit-sizes. Would you be able to scale this up to say, 4 bits? That's a good size for a logic unit, since it lets you show all 4 combinations of inputs.

I agree about the LU part But i don't use a XOR gate. If you download the map i can explain what i did there. I just went for the size.
What it does is there is an OR and an AND gate. Just their inputs are changed. Also about the invert part i also made 2 lines. One inverted and one normal. I'm just switching between them.

I may try to make a 4-bit version. Actually, i'm starting Minecraft right now!

EDIT: I just realized i becomed a Mathematical Dessert!

You might not THINK that you used XOR gates, but if you make a Truth-Table for "Switching Between Normal or Inverted Output" you'll be in for a funny surprise. XOR/XNOR gates are very commonly used as "Conditional Inverters". ALUs are, by weight, mostly XOR gates, and that's not just because of their Adders.

Let A be the input signal, and let C control whether it gets inverted or passed through straight. C=1 is inversion.

NAND

NOR

OR

AND

Its speed is around 2-4 ticks(i didn't measure it, just guessing).
