Ive currently got an application running on PowerPC with a customised
BSP, with RTEMS. It works great, and has for years. Its currently using
RTEMS 4.6.2. We dont use the Posix API in RTEMS, but the native RTEMS
calls for threads, semaphores, etc.
Now, ive got to make a native Linux version of this application.
The choices are:
1. Change all of the calls to Semaphore/thread calls compatible with
Linux, and conditionally build my program. (big job).
2. Use this "unix - Synthetic target CPU".
Is this "unix - Synthetic target CPU" suitable for this? Is it robust
enough for a production application? Does it introduce much overhead?
Is it just a wrapper to the native threading/semaphore calls of the OS?
I still need this program to work on my embedded system, and I wont use
the Posix api on RTEMS, cause i need RTEMS to be as small as possible.
Any information (or pointers to information) anyone can give on the
"unix - Synthetic target CPU" would be appreciated.
