Don't know whether anyones familar with rate monotonic and scheduling of real time systems, but here it goes: Task A (Period = 10 msec, CPU time = 2 msec) Task B (100, 6) Task C (250, 11) Task D (500, 5) Task E (250, 15) Task F (100, 6) Task G (500, 5) Task H (1000, 20) Task I (2000, 15) Question: During the actual operation of the system the driver may press the brake pedal at most 4 times per second. Pressing the pedal turns the system off. This process requires a worst case of 35 msec of cpu time and must respond within 90msec. Explain how you would incorporate this process into the above model. IS THIS A MATTER OF:- THE 4 TIMES PER SECOND IS THE PERIOD (250msec), BUT IT IS THE DEADLINE OF 35msec THAT THE TASK MUST RESPOND BY SO WE WOULD USE THIS AS THE PERIOD (PERIOD = DEADLINE)?
