Suppose that a machine has 42-bit virtual addresses and 32-bit physical addresses. a. How much RAM can the machine support (each byte of RAM must be addressable ? b. What is the largest virtual address space that can be supported for a process? c. If pages are 2 KB, how many entries must be in a single-level page table? d. If pages are 2 KB and we have a two-level page table where the first level is indexed by 15 bits, then how many entries does the first-level page table have? e. With the same setup as part (d), how many entries are in each second-level page table? f. What is the advantage of using a two-level page table over single-level page table? 2
