4-bit CPU

This is a 4-bit CPU I made. It technically can still handle 7 more instructions. But in order to make anything larger, I'll have to learn more complex computer architecture, my next goal is to make at least an 8-bit CPU with RAM (64 addresses I think)

I did NOT use any modding whatsoever.

You know you could have combined to sub, add, xor, or, and, nand, nor, and xnor all into one alu, right?

That is do-able, but it would bakr a very large chip you'd have to fit in there, with the smaller chips you can the wires a little neater.

Yes I do know that, everything below the double blue wires basically is the ALU. I was trying to make the largest single chip CPU I could, 1b, 2b and 4b all fit on one screen but anything larger will have to be split up into more chips. With my next 8b version, I will get rid of all the 16-1 MUX's and replace it with RAM. I appreciate the input, thank you (:
