Answer #1

Virtual Address trace is as below:

VA: 0: 0\ast00002ae2 \ast \rightarrow Not Valid (0*8000002c)

VA: 1: 0\ast00002265 \rightarrow PFN (0*800000f2)

VA: 2: 0\ast00003a44 \rightarrow Valid Bit (0*00000000)

    Suppose a machine does not use a multi-level page table. Suppose further, that the system uses a 54-bit virtual address and a 30-bit physical address. If the page size is 16K, how many entries should you have in the page table? You may express the answer as a power of 2. (1) Is the decision to have a single level page table a reasonable one? Explain (2) If you are to use the inverted page table in this system, what...

    Assume a 128KB virtual address space, with page size 64 bytes. a) What is the number of entries in the linear page table for these parameters? b) If each page table entry requires 4 bytes, what is the space occupied by a page table? c) If at any point only 1% of the actual translations in the page table are valid, does a two- level page table improve the space consumption? Explain with detailed calculation.
