Design a system using PCP for three tasks with the following priorities and resource requirements: Task A (priority 1) needs Resource R1, Task B (priority 2) needs Resource R2, and Task C (lowest priority) needs both R1 and R2. Discuss how PCP prevents priority inversion.
💡 Hint: Map out task interactions with resources and define ceiling priorities.
Consider two tasks, T1 (high priority) and T2 (low priority), where T1 is waiting for a resource held by T2. Explain how implementing PCP would resolve the priority inversion and describe potential drawbacks.
💡 Hint: Reflect on priority dynamics and limited resource sharing.
