I have 3 8-bit std_logic_vectors A, B, C. If I include the unsigned.all library, would the code correctly perform the following?:
Code: 
C <= A + B;
C <= A - B;
C <= A and B; -- bitwise addition
Also for multiplication, lets say I have a 16-bit vector called D. Would the following do what I want?:
Code: 
D <= A * B;
C <= D(7 downto 0); -- only interested in the lower 8-bits since C can't hold anything larger
Thanks for any help.
 

Yes It will work! Checkout yourself!
 

Hi,

For C <= A and B, it is always better you use the following syntax,

for i in 0 to 7 loop

C(i) <= A(i) and B(i);

end loop;


Rest all seems to be okay.
