7. Process Synchronization in Real-Time Systems
Process synchronization is crucial in real-time systems to manage concurrent execution of tasks sharing resources. It helps prevent issues like race conditions, deadlocks, and priority inversion, ensuring system reliability and predictability. Various synchronization mechanisms such as mutexes and semaphores are employed for effective task coordination and communication.

What we have learnt
- Process synchronization ensures safe and coordinated task execution in real-time systems.
- Mutexes, semaphores, event flags, and queues are fundamental synchronization primitives.
- Avoiding race conditions, priority inversion, and deadlocks is essential for maintaining system integrity.
Key Concepts
- -- Process Synchronization
- The coordination of simultaneous processes to ensure safe and consistent execution.
- -- Critical Section
- A section of code where shared resources are accessed and must be protected from concurrent access.
- -- Mutex
- A synchronization primitive that allows only one task to hold the lock and access a critical section at a time.
- -- Binary Semaphore
- A semaphore that allows access to shared resources without tracking ownership.
- -- Priority Inversion
- A scenario where a lower-priority task holds a resource needed by a higher-priority task, causing delays.
