Rate monotonic Analysis (RMA) is a model for predicting whether or not a system will meet its timing as well as throughput requirements when the system is operational. To build systems that are reliable and deterministic, the timing behavior of the tasks in a program must be predictable. If the system is predictable, it can be formally analyzed. RMA is one analysis tool that allows the designer to determine ahead of time whether the system will meet its real time requirements.a) The figures below represent a real system with three multi-threaded tasks. Task A is scheduled every 10 ms and is the highest priority. Task B is scheduled every 20 ms, and Task C scheduled every 40 ms. The execution times for all three tasks in table 1 are WCET. Will this system meet all of its deadlines based on RMA formula calculations? If not, why?b) What are practical ways for estimating WCET?
