Hi Sindhuja, I'm not sure exactly what you're looking for when you say "base and offset." I believe you can query the base page size from the ISA (I forget the exact function). With that you can divide and use modulo to compute the VPN/PPN and the offset. You can also look at the TLB code to see how it computes these things.
