The key to the robustness of a real-time operating system is the set of object classes that it employs. RTXC Quadros makes use of a set of object classes that provide a rich environment for real-time applications in each of the four RTOS frameworks.

RTXC Quadros object classes include:

• Tasks, Levels and Threads for managing code entities
• Semaphores for event synchronization
• Queues, Mailboxes and Messages, and Pipes for moving data
• Event Sources, Counters and Alarms for generalized counting and time management
• Memory Partitions for managing RAM
• Mutexes for exclusive access to resources
• Exceptions for versatile interrupt management
