2. Segment Tables

Base and bounds registers for each segment

Example: 32-bit virtual address space, 4KB pages, three segments: code, heap, stack

2-bit segment selector: 00 unused, 01 code, 10 heap, 11 stack

TLB miss handling:

  SN = (VirtualAddress & SEG_MASK) >> SN_SHIFT

  VPN = (VirtualAddress & VPN_MASK) >> VPN_SHIFT

  AddressOfPTE = Base[SN] + (VPN * sizeof(PTE))

specify SEG_MASK, SN_SHIFT, VPN_MASK, VPN_SHIFT: ________________
