I have to use a carry look ahead adder component (32bit), to implement a module able to perform addition (both signed and unsigned) , subtraction(signed and unsigned).
The only issue is the unsigned subtraction...how do I can do it? (in signed case I convert the number to 2's complement)..
thanks in advance..
I got a feeling that the signed/unsigned part comes free - if you just implement the circuit for addition / subtraction.
You can find a lot of inspiration at this site.
Thanks a lot..I'll try right right now..
