hi, <br> VxWorks 6.x have the Real-Time Process (RTP) extension.<br> I think we also can implement the RTP in RTEMS.<br> The Idea is :<br> 1 RTP contains 1~n user-level rtems-task, and process the virtual memory related things.
<br> 2 the mapping relation of virtual memory :phyiscal memory is 1:1 <br> 3 the user-level task in RTP can access kernel function by syscall<br> 4 the user-level tasks and the kernel-level tasks are in the same scheduling strategy.
<br><br> the advantage of RTP is:<br> 1 the crash of user-level tasks in RTP can not destroy user-level tasks in other RTP and the kernel.<br> 2 compatible with the old task model.<br> 3 the context switch is faster than that of general OS (such as linux)
<br> <br> anyone have some advices on RTP in RTEMS?<br><br>Regards<br><br> skyeye.rtems<br><br>
