RTEMS (Real-Time Executive for Multiprocessor Systems) is a commercial grade real-time operating system designed for deeply embedded systems. It is a free (as in beer and speech) open-source solution that supports multi-processor systems.

RTEMS is designed to support applications with the most stringent real-time requirements while being compatable with open standards such as POSIX. It's been ported to over ten processor architectures including ARM, PowerPC, i386, M68K, Coldfire, MIPS, SPARC, SH, H8, and C3x/C4x DSPs.

Using the GNU tools for cross development, you can use any number of systems as development hosts including both Unix and Windows platforms.

Here are some key features of "RTEMS":
realtime system design
semantics of BSP building and maintenance
driver development for clock, timer and RTC drivers
console drivers for raw and termios mode
network drivers
BSP structure
handling of target depenencies
Classic API
POSIX API

What's New in This Release:
This release addresses six problem reports filed by users against previous releases.
Five of these were Board Support Package-specific, and one was a cross-platform bug which occurred when deleting an instance of a per-task variable.
