Hello Everyone,

In my computer architecture lesson, we were designing ALU, our lecturer wanted us to make that more complicated. I couldnt do "shr" and "shl". Before that, I've not been able to do that, too.
Can you help me about it?

Attachments, the ppt of lesson and photo of circuit.
The program I need to use is the Logisim.
I couldnt connect logic circuit to arithmetic logic and both to 4x1 MUX.

Btw, I forgot to add what I already draw. I couldnt edit the first post either.
Could you combine this post to first?

A .zip file is allowed, but it probably won't get opened all the same - people don't like opening these sorts of files.

You should post screenshots of your work.
