How do Embedded Systems Ensure Real-Time Performance?

Embedded systems ensure real-time performance by using Real-Time Operating Systems (RTOS) that prioritize tasks based on urgency and deadlines. These systems are designed to respond to inputs or events within strict timing constraints, often measured in milliseconds. Efficient scheduling algorithms, low-latency hardware, and minimal overhead in software execution help maintain predictable behavior. Additionally, embedded systems often use dedicated resources and avoid unnecessary multitasking to reduce delays. Real-time constraints are validated through testing methods like worst-case execution time analysis. Mastering these techniques is essential in any embedded system certification course.
