What are the challenges of scheduling in real-time systems?

Scheduling in real-time systems involves ensuring that tasks meet their deadlines, which can be challenging due to resource constraints and varying task priorities.

Can you explain the difference between hard and soft real-time systems?

Hard real-time systems require strict adherence to deadlines, while soft real-time systems can tolerate some delays without catastrophic consequences.

What algorithms are commonly used for scheduling in these systems?

Common algorithms include Rate Monotonic Scheduling (RMS), Earliest Deadline First (EDF), and Least Laxity First (LLF). Each has its own advantages depending on the system requirements.

How do you handle resource contention in real-time scheduling?

Resource contention can be managed using priority inheritance protocols or by implementing resource reservation techniques to ensure critical tasks have access to necessary resources.
