if you want to use ram then use two rams one for s1 and one for s2 then subtract addresses without the need for loop

--- Quote End ---

actually i use dual port ram for s1 and s2 and make this code

if data_a = data_b then

distance <= addr_a - addr_b;

end if;

the big problem is if and only if data_a = data_b at the same clock cycle not for all data index ,you understand me
