Here is the mem_map for a process:

	Virtual	Physical	Length
Text	0	0x151A	2
Data	0	0x151C	1
Stack	0x20	0x153C	1

     pa = bpa * csize + va - bva * csize

Example 1:
  csize = 4096 = 0x1000 (bytes)
  va = 0x00000a48 (bytes)
  Segment: Data
  bva = 0  (clicks)
  bpa = 0x151C (clicks)

  pa = 0x151C * 0x1000 + 0x00000a48 - 0 * 0x1000 = 0x0151CA48

Example 2:
  csize = 4096 = 0x1000 (bytes)
  va = 0x00020DE8 (bytes)
  Segment: Stack
  bva = 0x20  (clicks)
  bpa = 0x153C (clicks)

  pa = 0x153C * 0x1000 + 0x00020DE8 - 0x20 * 0x1000 = 0x0153CDE8
