Question 1
Given four tasks with execution times and periods: Task A: C=2ms, T=5ms; Task B: C=1ms, T=3ms; Task C: C=3ms, T=6ms; Task D: C=2ms, T=4ms. Calculate total utilization and assess if schedulable using Liu & Layland's bound.
💡 Hint: Calculate each task's ratio and sum it, then compare.
Question 2
Create a task set of three tasks with varying WCRT values, then establish if they are schedulable using RTA. Calculate WCRT for each and evaluate against deadlines.
💡 Hint: Use the interference caused by higher-priority tasks during your calculations.
