Real-time processing is essential in embedded systems used for IoT applications because it ensures timely and accurate responses to changing environmental conditions. In critical sectors like healthcare, transportation, and industrial automation, even a slight delay can lead to failures or safety risks. Real-time systems process data as it arrives, enabling devices to react instantly to inputs such as sensor data, motion detection, or temperature changes. This capability enhances system reliability, performance, and user experience. Without real-time processing, IoT devices would struggle to maintain synchronization and responsiveness.
