Question

Consider a system of two periodic tasks: T1=(4.5, 2), T2=(6,2). They are scheduled by RM. An aperiodic task A with execution time 1.5 is released at 0.1. Construct the schedule of the system in the first 15 units of time in each of the following three cases: a. [5pts] A is scheduled at the background of T1 and T2. b. [5pts] A is scheduled using a simple polling server Ts=(4, 0.5). c. [5pts] A is scheduled using a deferrable server Tds=(4, 0.5).

Step 1

In this case, A is scheduled in the background of T1 and T2. Since T1 has a higher priority than T2, we will first schedule T1 and then T2. At time 0, T1 is released and starts executing. It will execute for 2 units of time and complete at time 2. At time 2, Show more…
