The key to the robustness of a real-time operating system is the set of object classes that it employs. RTXC 3.2 makes use of a set of object classes that provide a rich environment for real-time applications, including:

• Tasks for managing code entities
• Intertask communication and synchronization via Semaphores, Mailboxes and Messages, and Queues
• Efficient time management with one-shot and periodic Timers
• RAM management through static and dynamic Memory Partitions
• Resources for exclusive access to entities
