Address Translation in Paging
• Step 2 — from logical address & to information to physical address
(frame)
• From the example in Figure 7.12(a) [Stalling]
• Logical address is the same as 7.11, which is 1502, which is 0000
0101 1101 1110 in binary
• The page information, 0000 01, refers to the row 1 of Page Table.
• In row 1 of Page Table, it contains number 6, or 0001 10.
• This is the frame number of the physical memory.
• The offset of the logical address is also used as the offset of the
frame.
• Therefore, the data is at offset 478 of frame 6 in the physical
memory
