Some of the supported features are:
- A familiar POSIX-compatible interface.
- True simultaneous preemptive multitasking.
- Advanced cryptography and a security-centered architecture.
- Mandatory Access Control (MAC).
- Highly configurable, hard real-time scheduling.
- Support for several architectures and boards.
