QUESTION 1. (20 Marks] A paging system with an X-bytes of logical memory with some portions of logical addresses (decimal) with its contents as shown in Table I need to be mapped to an Y-bytes of physical memory based on the complete 23 entries for a page table shown in Table 2. Assume that each entry size is 22-bytes and the physical memory size is 26 frames. Answer the following questions. Table 1 Table 2 Content B Logical Address 0 1 2 Pagen 0 1 2 3 4 5 6 7 A D G Frame 20 45 5 12 10 9 30 4 4 s E 19 20 21 22 23 H F I (a) Calculate the size of X and Y. Show your working [4 Marks] (b) What will be the contents of frame 9? Justify your answer. [3 Marks] (c) How many bits will be used for the page number and frame number in logical memory address and physical memory address, respectively? Show your working. [4 Marks] (d) Calculate the logical address (decimal) given a physical address as 101101102. Show your working. [4 Marks] (e) Calculate the physical address of data E in binary of 8 bits. Assume that the initial offset is 0. Show your working. [3 Marks] (6) Write TWO consequences if the paging system resize the frame to 23-bytes? Justify each of your answer. [2 marks] 2019/2020-2
