Question
We have 4 periodical processes II₁, I2, I3 and II4, that process a video. We know their
periods P, and their running times C; (in milliseconds). For:
(a) the earliest deadline first (EDF) algorithm and
(b) the rate monotonic scheduling (RMS) algorithm
draw diagrams that displays the schedule for those processes for a period of 150 ms. The
times are the following:
Process P Ci
II₁
60 15
II₂
40 10
II 3
45 10
II₁
35 5
In the case of equal priorities the process that is already running has the priority. If this
is not the case then take the process with the lowest ID. Does any of the above algorithms
fail?
