I think you might be out of luck for this case. AdaCore Technologies 
supports ARM/XScale with a vxWorks target OS. I am not aware of any Ada 
compiler targetting windows CE or Windows XP Embedded (with an Xscale 
target)

As for Linux, I am not aware of any Linux targetted Ada compilers for 
Xscale.

You could try to talk to the people at AdaCore Technologies (www.gnat.com) 
and see if there is something
unpublished that meets your needs.


Greenhills (one of the other big Ada vendors) does not target Xscale with 
their Ada compiler but probably could be convinced but I don't think they 
support your desired target OSs (they tend to target either bare machine, 
vxWorks or their own embedded OS)

The rest of big the Ada vendors (IBM/Rational, OC Systems, DDCI, RRSoftware, 
Aonix) don't appear
to meet your needs either.

The other minor problem in your requirements is that you said it must be 
real-time...But Windows XP Embedded is not really real-time (though it is 
similar to Linux in that there are add ons to make it real-time like).
