RTOS Examiner-RTOS code analysis tool

Example

Creating, managing, and scheduling threads with specific priorities to simulate a real-time multitasking environment. For instance, using attributes like SCHED_FIFO in pthreads to enforce strict scheduling policies.

Scenario

A user is tasked to adjust thread priorities in a multi-threaded program ensuring that high-priority tasks like interrupt handlers execute before less critical tasks, thereby mimicking real-time constraints.

Example

Implementing mutexes and semaphores to manage resource access among multiple threads, ensuring data consistency and avoiding race conditions.

Scenario

Using semaphores to control access to a shared resource in a parking garage system where multiple threads (representing cars) attempt to access limited parking spots without conflict.

Example

Analyzing and resolving deadlocks using advanced algorithms and strategies like priority inheritance to prevent system halts.

Scenario

Resolving a potential deadlock in a dining philosophers simulation by implementing a system that uses both timeouts and resource hierarchy to prevent philosophers from indefinitely waiting for resources.
