+RTEMS is a freely available, royalty free real-time executive with
+multiprocessor capabilities.  RTEMS' design provides performance and
+capabilities are comparable to those of the best commercial executives.
+The directive execution times and other critical performance measures such
+as interrupt latency are best of class. RTEMS was developed by On-Line
+Applications Research Corporation (OAR) under contract to the U.S. Army
+Missile Command. 
+
+
+RTEMS includes support for multiple APIs.  Currently RTEMS supports a
+POSIX threads API, and an RTEID based API which is similar to pSOS+. 
+RTEMS includes a number of advanced real-time features including optional
+rate monotonic scheduling support, binary semapahores with priority
+inheritance, and watchdog timer functions. 
+
+RTEMS includes a port of the FreeBSD TCP/IP stack that has high
+performance on very modest hardware.  A remote debug server is supported
+on some targets that allows debugging across the network. 
+
+RTEMS provides a rich run-time environment with a reentrant C library,
+POSIX 1003.1b support, and file system support.  It also includes optional
+debug aids like stack overflow and heap integrity checking. 
+
+RTEMS is built using GNU autoconf and can be built on any host supporting
+the GNU tools including Linux, FreeBSD, NetBSD, Solaris, and MS-Windows to
+name but a few.  The current RTEMS release supports a the following CPU
+families: 
+
+  Motorola m680x0, m683xx, and ColdFire
+  Motorola and IBM PowerPC (4xx, 6xx, 7xx, and 8xx) 
+  Hitachi SH-1
+  Intel i386, i486, Pentium, and i960
+  SPARC
+  MIPS
+  HP PA-RISC
+  AMD A29K
+
+There are over 35 Board Support Packages included with RTEMS including
+BSPs for the SPARC and PowerPC simulators included with gdb.  There are
+numerous BSPs for CPUs targetting the embedded market such as the Motorola
+m683xx and mpc8xx series which support the on-CPU peripherals.
