A system implements paging using a page size of 4096 (2^12) bytes.

The diagram shows the current state of the TLB, CoreMap, Swap Space and
page tables for only two of several executing programs (Program A and
Program B).

Note that VPN refers to the virtual page number and PFN refers to the
corresponding physical frame number.  D, U, V, and RO are the dirty,
use, valid and read-only bits, respectively.
In this example the TLB updates the Use and Dirty (Modified) bits
on references to a virtual page.

The SW entry (right most column in each page table) is used to denote
the sector on the swap disk used to store the page.

A value of -1 in the SW column indicates that the page is not stored
on the swap disk.

An X on the swap disk indicates that the sector is used.

Assume that:
 o the next three potential victims chosen by the page
   replacement algorithm are (4, 0, 3);
 o the next three potential victims chosen by the TLB
   replacement algorithm are (1, 2, 0);
 o the next three potential free sectors used 
   on the swap disk are (2, 3, 5).

List all steps performed by the operating system and MMU when executing
the following sequence of memory references.

Part 1) Process A does a load from address 0x00003C9A.
Part 2) Process A does a store to address  0x00002F08.
