Embedded Development with UML 2

Speaker: Ken Webb

Many embedded developers view the Unified Modeling Language (UML) with disdain as just a bunch of bubble diagrams. In fact, with the recent introduction of version 2, UML now incorporates the key concepts used by former local firm ObjecTime in their product for real-time and embedded software development. It is now possible to develop and maintain complete applications, with all the code, using UML 2.

I propose to do a presentation for the December meeting describing these concepts, and how I have implemented them in my open-source project Xholon. It will conclude with a demo of Xholon. This will start with a short session with a third-party UML 2 tool, will continue through code generation, to running the generated application using the Xholon runtime framework.


  • Introduction
  • Some concepts behind UML 2 and Xholon: Object-oriented (class, inheritance, etc.), Composite structure, Ports, State machines, Message passing, Code as an integral part of the UML 2 model, Forward engineering with code generation; no reverse engineering
  • Xholon: Goals, Current status
  • Worked Example (demonstrated on a Linux laptop)
  • Wrapup
