What is priority inheritance in real-time systems?

Priority inheritance is a protocol used in real-time systems to prevent priority inversion, where a lower-priority task holds a resource needed by a higher-priority task.

Can you explain how it works?

Sure! When a lower-priority task holds a resource and a higher-priority task needs it, the lower-priority task temporarily 'inherits' the higher priority to complete its task and release the resource.

What are the benefits of using priority inheritance?

The main benefits include reduced blocking time for high-priority tasks and improved system responsiveness, ensuring that critical tasks meet their deadlines.

Are there any drawbacks to this approach?

Yes, potential drawbacks include increased complexity in implementation and the possibility of priority inversion if not managed properly.
