As automotive ECUs grow in complexity, with ever-tighter timing constraints and increasing safety demands, the operating system can be the difference between predictable performance and a critical bottleneck.

In this technical webinar, ETAS experts take an in-depth look at RTA-OS, the AUTOSAR Classic real-time operating system engineered for minimal footprint, deterministic execution, and functional safety. You’ll learn how RTA-OS is designed from the ground up to meet the demands of safety-critical automotive systems.

The experts explore the architectural principles behind RTA-OS, including compile-time configuration, static scheduling, zero-overhead abstractions, and hardware-aware implementation. The session also includes a technical comparison with FreeRTOS and SafeRTOS, highlighting key design differences, trade-offs, and why RTA-OS is often selected for safety-critical automotive applications.

Key topics and takeaways:

• How RTA-OS achieves its exceptionally small footprint and deterministic behavior
• Why and when to choose RTA-OS over FreeRTOS and SafeRTOS
• How to meet functional safety requirements without sacrificing real-time performance
• Why RTA-OS is well-suited for safety-critical ECUs with tight timing and memory constraints
• How proven scalability and long-term support can reduce risk and cost over the lifetime of your project
