Consider a paged memory system with a logical address space consisting of 64 pages of size 1 Kbytes each. The physical memory space is 256 Kbytes. All addresses are byte addresses. a) What is the size of a logical address and what is the size of a physical address? b) Show the format of a logical address indicating what fields it consists of and the sizes of the fields. Describe exactly how a virtual address generated by the CPU is translated into a physical main memory address. c) d) What is the size of the page table, i.e., how many entries does it contain and what is the size of each entry (disregarding the control bits)? e) What is the effect on the size of the page table if the physical memory space is doubled? f) What is the effect on the size of the page table if the logical address space is doubled?
