Consider the following task set, where the numbers in parenthesis are the release time, execution time, and priority (the higher the number the higher the priority). Draw a schedule diagram for the five tasks from time 0 through 20 (use timelines below) using a) the NPCS protocol, b) priority inheritance, and c) the priority ceiling protocol. For each task, its corresponding critical section starts 1 time unit after the task started executing. Each nested critical section starts 1.5 time units after the begin of the previous critical section. Task i Parameters Resources 1 (7,3,5) requires resource R1 for 1 time unit 2 (5,3,4) requires resource R2 for 1 time unit 3 (4,2,3) requires no resources 4 (2,6,2) requires resource R1 for 4 and resource R2 for 1.5 time units (nested) 5 (0,6,1) requires resource R2 for 4 time units
