Real-time processing is a critical aspect of embedded systems because these systems often interact directly with the physical world, where timely responses are essential. In many applications—such as medical devices, automotive systems, robotics, and industrial automation—a delay of even a few milliseconds can lead to system failure or safety hazards. Real-time processing ensures that tasks are completed within a specified time constraint, which is crucial for maintaining system stability and reliability.

There are two types of real-time systems: hard real-time, where missing a deadline can result in catastrophic failure (e.g., pacemakers or anti-lock braking systems), and soft real-time, where performance degrades but the system still functions (e.g., video streaming). Embedded systems must be designed with appropriate scheduling algorithms and hardware resources to meet these timing requirements.

The importance of real-time capability lies in its ability to guarantee predictable behavior. It enables the embedded system to respond quickly and consistently to external inputs, ensuring functionality, safety, and user satisfaction across a range of applications.
