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.
