Answer : 4 Exp : Fetching lw : CPU has address, say A1, from where to fetch lw. We’ll look into page table, in worst case, page table may not be present in the memory as it is given in the question that “Page tables are not locked in memory and may be swapped to disk”. So, we bring page table. 1 page fault. Now, it could happen that the page containing lw word is not in memory, so we bring it, 1 page fault. So, fetch cycle, in worst case, may have 2 page faults. Decoding lw :… [...]
