2. Figures 4 and 5 show a circuit for solving the priority of the interrupt requests from four devices and the corresponding characteristic table of the priority encoder respectively. Figure 4 Figure 5 (a) Determine the priority of the devices. (b) Determine the interrupt vector number of the interrupt service routine serving Device C. (c) Suggest a method to ignore the interrupt requests from devices A and C only. (d) Figure 6 shows the content of part of the main memory system. If the system operates in the real mode, determine the starting address of the interrupt service routine for Device C. rigure o (e) Give the flowchart of the interrupt service routine for case 3. You may use the elements shown in Figure 7 to construct your flowchart
