Question 1 (a)It is detected that a faulty embedded system is unable to generate an output for the Boolean expressions below. You were tasked to use only algebraic method generate the output I. X'YZ' + X'YZ + XYZ II. A+ [BK(AC)' + D]' (6 marks) (7 marks) (b) Justify why the transition from the first to the second generation of computers was referred to (then) as successful. Question 2 (7 marks) A three level cache computer has main memory access time 800 ns, first, second and third level cache access time 300 ns, 250 ns and 180 ns respectively. If the hit ratio of the first, second and third cache are 0.7, 0.5 and 0.3 respectively a) Deduce the appropriate equation to calculate the average access time. (5 marks) AP b) Using your equation in "a" above, find the average access time (9 marks) AN c) If cache 3 goes down, but it does not affect the operation of the computer, refine your equation in "a" above and compute the new average access time (6 marks) EV
