Q2 (a) Discuss how implementation of interrupts can aid in achieving multi-tasking in sequential programming. Support your discussion by relating to time-triggered and event-triggered tasks. (5 marks) (b) The control system for an embedded system has 4 concurrent tasks running on a single microcontroller as given in Table Q2(b). Task 1 and 3 are hard real time, while Task 2 and 4 are soft real time. Task 1 2 3 4 Period (ms) 80 30 50 40 Table Q2(b) CPU resources (ms) 10 10 2 10 Deadline (ms) 80 (hard) 35 (soft) 50 (hard) 45 (soft) (i) (ii) Construct an appropriate priority assignment for each of the 4 tasks according to the rate monotonic scheduling (RMS) algorithm. (4 marks) Assess the ability of each task to meet its deadline based on the worst-case completion time of RMS calculation.
