URGENT
Suppose the page table for a process currently executing on the processor looks like the following. All addresses are memory byte addresses, and addresses in the main memory and processes start from zero. The page size is 512 bytes.
Virtual page number | Valid bit | Page frame number |
0 | 1 | 3 |
1 | 1 | 8 |
2 | 0 | 4 |
3 | 1 | 1 |
4 | 0 | 6 |
5 | 1 | 0 |
What physical address, if any, would each of the following virtual addresses correspond to? (Indicate when a page fault occurs). virtual page number = address / table entry size offset = virtual address mod table entry size frame number multiplied by page size and add in page offset to get address
