Verify the Schedulability under EDF and construct EDF schedule of the following tasks set in the interval (0 to 20 units of time). Draw a timing diagram showing task execution for 20 units of time. Consider the following task set: 1 {1, 5, 4}, 2 {2, 8, 6}, and 3 {1, 4, 3}. Here, the notation i { ei , pi , Di } gives the execution time, ei , period, pi , and relative deadline, Di , of task i .
