Actel M1 and Kiel Realview RTX

 Actel M1 and Kiel Realview RTX

I am considering using an ACTEL FPGA with a Cortex-M1 IP processor.
After reading the Actel documentation it states the current implementation has "no OS extensions". I think not having the OS extensions removes the following features from the Cortex-M1
1) 2 stacks pointer (leaving only 1 stack pointer).
2) The SVC assembler instruction for software interrupts (protected/user mode).
3) System timers - for systick?

The question is, can this be made to run the Kiel RTX OS? It is listed on the Keil device list but I am having some doubts about this now. Is anyone using the Actel Cortex-M1 and RTX together?

Thanks for your help,
Stuart.

The current implementation of the Cortex-M1 Core by Actel doesn't have the OS extensions. Therefore Keil RTX OS (or any other OS) currently can't be used for this. Only non RTX application will run.

Actel says that in the future versions this will be available (I suggest you contact Actel for more info).
