Counter intuitively it is possible that this is holding Ada back. A lot of
 Ada code cannot run without some fairly complex runtime support due to
 tasks, protected objects, finalization etc.. Runtimes have to be developed
 for each chip instead of each cpu. Atleast I assume that that is why these
 features are not available to e.g. the light cortex-m33 or cortex-m4 or
 cortex-m0+ runtimes. This requires rewriting code which isn't required with
 equivalent C code such as containers and ip stacks etc.. Even support for
 the Ada interrupt package is missing but it looks like porting that support
 to chips is less work and research.

If you need advanced multi core support then using an OS seems like a more
 suitable situation to be in to me.
