RTEMS is a real-time executive in use by embedded systems applications around the world and beyond.

If you are new to RTEMS and the community, welcome. To use RTEMS you need to build a cross-compiler tool set and RTEMS. The Tutorials section below and the Quick Start Guide? are a great place to start with. We have examples that guide you through some simple example programs like Hello World. The various simulators such as GDB SPARC are easy to use and lets you see RTEMS running right on your host computer. Enjoy your time with RTEMS and please drop by the User Mailing List or IRC channel #rtems on Freenode.
