As far as working on a range of CPUs, Forth is again a great option
because it only really requires some headers to locate the peripherial
addresses, and a few communication functions to work with the host PC.
 Porting to a new processor is (supposedly, and if you know what
you're doing) a fairly straightforward operation.

My professor had a Forth implementation running on an ARM-Cortex M3 in
class last week.  He hasn't uploaded anything yet, but I'm guessing
that he will make them available shortly.  I'll ask him about it in
class tonight, and let you know.

For reference, his PFAVR application runs Forth on an AVR
microprocessor.  It takes 32k of external RAM, but you could probably
tweak that down significantly, especially if you're willing to make
the interpreter run in Flash, and keep only the dictionary and stacks
in RAM.
The page is at:
http://claymore.engineer.gvsu.edu/~steriana/Software/pfavr/index.html
That link also has some introductory material and links to other resources.

I'll let you know what he's planning to do with his ARM Forth
implementation in about 10 hours.
