use two single port rams one for s1 and one for s2 then address subtraction applies.

If you also want to write inputs to the rams then use two dual port rams again one for s1 rd/wr and one for s2 rd/wr.

It really depends how you are going to get your inputs s1/s2 in the first place which you haven't told us yet.
