Question
Suppose there are two periodic/isochronous requests P1 and P2:
P1: (35, 70)
P1: (40, 95)
Question 4.2.1 Please specify the process running sequence of P1 and P2 (such as, P1,P1,P2,P2 ...)
using the EDF scheduling between the time t between 0 and 285, namely te [0, 285].
Question 4.2.2 Please explain the system status when te [185, 190] and explain why.
Question 4.2.3 Suppose at t= 280, a new periodic request, P3 (30, 40), enters the system. According to
the EDF scheduling algorithm, can P3 be admitted or not? And, explain why.
