regarding you code about register how i can find index in vhdl code.

The index of register would be the loop 


for i in 0 to n-1 loop
    for j in 0 to n-1 loop
       if s1_shift(i) = s2_shift(j) then
           d(i) <= j-i;
       end if;
   end loop;
end loop;

you will get d(0) ~ d(n-1) as distance then you compute it further

you need to get the type conversion right and test the code idea.
