In embedded systems, interrupts are essential for handling time-sensitive tasks and events. They allow the processor to temporarily suspend its current task and switch to a different task or process that requires immediate attention. This is crucial for real-time applications where timely responses are critical, such as in automotive systems, industrial automation, and medical devices.

When an interrupt occurs, the processor saves its current state and jumps to an interrupt service routine (ISR) to handle the interrupt. Once the ISR completes, the processor returns to the saved state and resumes its previous task. This mechanism ensures that important events are handled promptly without disrupting the overall system operation.

Understanding interrupts is fundamental for embedded systems developers, as they enable efficient and responsive system design. To gain a deeper understanding of interrupts and other key concepts in embedded systems, consider enrolling in embedded certification courses. These courses provide comprehensive training on embedded systems design, programming, and optimization, helping you become proficient in this specialized field.
