Welcome to the RTEMS home page!
The RTEMS Project was accepted as a Google Summer of Code 2008 mentoring organization. Students, please visit our Open projects page and start asking questions about them on the RTEMS Users mailing list about projects you are interested in.
RTEMS is the Real-Time Operating System for Multiprocessor Systems. It is a full featured RTOS that supports a variety of open API and interface standards.
Major decisions about RTEMS are made by the Steering Committee, guided by the Mission Statement.
We encourage everyone to contribute changes and help testing RTEMS, and we provide access to our development sources with anonymous CVS and snapshots .
We strive to provide regular, high quality releases, which we want to work well on a wide range of embedded targets using cross development from a variety of hosts including GNU/Linux, FreeBSD, Cygwin, and Solaris.
- Active development (mainline): will become 4.9 (obtain from CVS)
- Active release branches:

Upcoming Events
- Embedded World 2008
- the embedded brains GmbH will be present at the Embedded World 2008 trade show in Nuremberg, Germany from February 26 until February 28 2008, Thomas Doerfler and associates will be in stand 115 in hall 11.0. They will be showing off RTEMS and some of their RTEMS-based customer applications. Hopefully we can discuss the benefits of using RTEMS compared to closed source RTOSes. We will also present a world innovation: The first RTEMS based chocolate slot machine, which can be controlled via SMS from any cell phone. Please take this opportunity to meet one of the key members in the RTEMS Community meet face to face. Getting him to talk about RTEMS should be as easy as taking candy from a baby but that will NOT be necessary in this booth. :-)

News/Announcements
- February 14, 2008 - 4.8.0 Released
- Happy Saint Valentine's Day!!! Today there were two RTEMS releases. The first of these is the long anticipated 4.8.0. 4.8.0 is the first release from the 4.8 release series and represents a long awaited step forward from the 4.8 releases. There have been many improvements to RTEMS itself including optional nanosecond timing granularity, smaller executables, a port to the Blackfin, and new POSIX services. The GNU/Linux RPMs have been updated and there are now MinGW hosted tools for MS-Windows users. On either hosts, users should be able to get started with RTEMS in a matter of minutes. For more details, see the 4.8.0 release information. Please note that if we forgot to include anyone's work in the release information, it is an accident. Please email and we will add the information.
- February 14, 2008 - 4.7.2 Released

details associated with a release.
