2RTEMS is a freely available, royalty free real-time executive with
3multiprocessor capabilities.  RTEMS' design provides performance and
4capabilities are comparable to those of the best commercial executives.
5The directive execution times and other critical performance measures such
6as interrupt latency are best of class. RTEMS was developed by On-Line
7Applications Research Corporation (OAR) under contract to the U.S. Army
8Missile Command.

11RTEMS includes support for multiple APIs.  Currently RTEMS supports a
12POSIX threads API, and an RTEID based API which is similar to pSOS+.
13RTEMS includes a number of advanced real-time features including optional
14rate monotonic scheduling support, binary semapahores with priority
15inheritance, and watchdog timer functions.
16
17RTEMS includes a port of the FreeBSD TCP/IP stack that has high
18performance on very modest hardware.  A remote debug server is supported
19on some targets that allows debugging across the network.
20
21RTEMS provides a rich run-time environment with a reentrant C library,
22POSIX 1003.1b support, and file system support.  It also includes optional
23debug aids like stack overflow and heap integrity checking.
24
25RTEMS is built using GNU autoconf and can be built on any host supporting
26the GNU tools including Linux, FreeBSD, NetBSD, Solaris, and MS-Windows to
27name but a few.  The current RTEMS release supports a the following CPU
28families:
29
30  Motorola m680x0, m683xx, and ColdFire
31  Motorola and IBM PowerPC (4xx, 6xx, 7xx, and 8xx)
32  Hitachi SH-1
33  Intel i386, i486, Pentium, and i960
34  SPARC
35  MIPS
36  HP PA-RISC
37  AMD A29K
38
39There are over 35 Board Support Packages included with RTEMS including
40BSPs for the SPARC and PowerPC simulators included with gdb.  There are
41numerous BSPs for CPUs targetting the embedded market such as the Motorola
42m683xx and mpc8xx series which support the on-CPU peripherals.
