Unsigned subtraction
Hi guys..
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.. andrew r. andrew_ross |

Hi
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. http://tima-cmp.imag.fr/~guyot/Cours...ish/Adspec.htm Jeppe jeppe |
