The clock speed of cortex-m4 is about 200MHz, which is not enough for image or complex data processing. So I want to use cortex-A9, and i'm wonder if the RTOS can be used in it ?
If not,can you give me some advice for complex algorithm processing issues? thanks a lot.
It seems FreeRTOS and some other RTOS support cortex-A8 cortex-A9 and cortex-R, showing below. And CMSIS-RTOS is a wrapped interface using other RTOS's apis , so can I use CMSIS-RTOS directly ?

I like to ask you a question about which chip manufacture you are interested in for Cortex A8 ot A9. I did a search on TIs website they have a Sitara Cortex A8 which has several RTOSs that can be used,
TI-RTOS, QNX Neutrino, INTEGRITY(Green Hills Software),
I just found a chart:

But so far if I search for CMSIS RTOS and Sitara wi;; not find anything about cmsis.
If you go to this page: http://www.keil.com/pack/doc/CMSIS/General/html/index.html
the introduction states CMSIS is just for Cortex M
yeah,it's just for cortex-m, maybe we can change a bit to support cortex-A.
