4. A system T has two periodic threads: T- Ti = (10.5). T2 = (14.6). (a) Is the system T schedulable according to the RMA principle? (b) Suppose thread T2 is more important than thread T1. Use the periodic transformation approach to modify the thread set so that the periodic threads are schedulable. Draw a timing diagram to show the RMA-based schedule of the threads. 4.
