At the risk of stating the absolutely obvious, I presume you've looked
at existing UML tools. I know that RoseRT from Rational generates code
from its state machines, and my team used it successfully in building
real-time embedded software in 1999. We were quite happy with the
performance of the resulting code in a pretty demanding environment.


You might also like to look at the ArgoUML open source UML CASE tool
(http://argouml.tigris.org), which includes code generation
functionality. The code generation functionality is still in relatively
early stages, but might be a useful forum for your discussing your work
(I declare an interest as an active member of the ArgoUML team).


Hope this helps.
