RTEMS

RTEMS is an open source RTOS that supports open standard application programming interfaces such as POSIX. It is used in space flight, medical, networking and many more embedded devices.

Features

• POSIX 1003.1b API including threads.
• VMEbus Industry Trade Association RTEID/ORKID based Classic API (similar to pSOS+).
• TCP/IP including BSD Sockets.
• GNU Toolset Supports Multiple Language Standards. Multitasking capabilities.
• Homogeneous and heterogeneous multiprocessor systems. Event-driven, priority-based pre-emptive scheduling.
• Optional rate-monotonic scheduling. Intertask communication and synchronization.
• Priority inheritance.
• Responsive interrupt management.
• Dynamic memory allocation.
• High level of user configurability.
• Portable to many target environments.
• High performance port of FreeBSD TCP/IP stack.
• POSIX standard file system semantics.
• GNU debugger. DDD GUI interface to gdb.
