Description: An alarm handler is a routine that executes in response to an alarm signal, often to perform critical tasks in real-time. In the context of real-time systems, this component is essential for ensuring that operations are carried out within specific deadlines. Alarm handlers allow systems to react quickly to external or internal events, ensuring that high-priority tasks are executed without delays. These handlers are fundamental in applications where time is a critical factor, such as in industrial control systems, medical devices, and navigation systems. The implementation of an alarm handler can vary depending on the system design, but it generally includes timer configuration and interrupt management to trigger the corresponding routine when a predefined time threshold is reached. This allows the system to maintain a high level of efficiency and accuracy in task execution, which is vital in environments where reliability and timeliness are paramount.
