An embedded system in a car achieve a set of three tasks: Read speed sensor (T1), Engine Monitoring (T2), and Speed Display (T3). The execution time C and the period P of each task are summarized in the following table: Task Ti C₁ (Execution time) P₁ (Period of task) U; (Utilisation) Task T₁ 20 4 120 Task T₂ 5. 20 Task T3 10 ( 40 60 TA 2 1. Compute the processor utilization of each task: 2. Compute the total utilization UT? B 3. Is the tasks set schedulable using Utilization factor test? P. 4. Complete the timeline for the different tasks. ✓ X 160 = 120 5. Determine the processor utilisation based on this diagram. 6. Compare it to the result obtained in 2). 7. A 4th task T4 is added to the previous system with C4-15 and P4-60. Determine the new UT and UB using the four tasks. Conclude about the schedulability. r 8. Considering the task priority, apply the response time for all tasks. 9. Complete the timeline for the different tasks. 10. Determine the processor utilisation based on this diagram. Conclude. العطفي ف
