Real-time scheduling under EDF and RM.

Three periodic processes with the following characteristics are to be scheduled: (D is the period and T is the total CPU time) D T p1 20 5 p2 100 10 p3 120 42 (a) Determine if a feasible schedule exists. (b) Determine how many more processes, each with T = 3 and D = 20, can run concurrently under EDF. (c) Determine how many more processes, each with T = 3 and D = 20, can run concurrently under RM
