Base 10 ALUs FTW, right?
How would you manage logic? :3

Don't think I'll implement any logic actually. It is not needed for most calculations so there's no real need that I can see. Branching will be implemented with zero checking and maybe carry overflow flags.

who needs logic anyways amiright?

It's not a real cpu/alu without logic

What? There is no need for logic in an alu at all.

Arthimetic(?) LOGIC unit.
But yeah, you don't need it, although you might want some sort of greater than/lesser than flag somehow somewhere.

Well, suppose I'll just call it the AU then
I will have a comparation (correct english?) flag, however I've never considered this to be a part of the logic. Maybe I got my terminologly wrong? Logic for me is only the logical operators on memory and the bitwise stuffs.On an unrelated note, some help with an IS would be appreciated. I am very bad at designing these so it would help me out alot. I'm thinking of a simple RISC system with 4-8 registers, add/subtract and right/left shifting. Branching will be both conditional and unconditional, with conditions being carry overflow and equal/less than zero. Any thoughts?
