= Potential Ports =


We are always interested in adding ports to other CPU families supported by the GNU tools.  If you are interested in working on a port or are ready to submit one, contact us.

 * Atmel AVR
 * Xtensa
 * Motorola MCore
 * Texas Instruments C6x
 * ARC
 * ...
= Obsoleted Ports =


An RTEMS port may be obsoleted for a number of reasons.  The CPU architecture may no longer be manufactured, interest within the embedded community has gone away, or the GNU tools may drop support it.  The following ports have been deemed obsolete and will be in no future RTEMS releases.

 * AMD A29K
 * Hewlett-Packard PA-RISC
 * Intel i960
 * OpenCores OR32
