3. Consider a fully associative TLB with a capacity of 16 virtual-to-physical page translations. Assuming that the physical memory has a capacity of 32K pages, each 2KB in size, answer the following: (a) How many bits are associated with each PTE (including one valid bit and one dirty bit)? (b) How many bits are associated with each page translation in the TLB (in- cluding one valid bit and one dirty bit)? (c) How many bits must the page table register hold? (d) How many bits of left-shifting must the PPN undergo for determination of the physical memory address of the first byte of a physical page? (e) How many address bits are required for the physical memory? What is the capacity of this memory in bytes? 3.
