ReaGeniX Programmer is for ...

• specification, design, and visual programming of
  • the state behaviour
  • the architecture
• special needs of embedded real-time software
• defining the system dynamics using
  • asynchronously communicating, concurrent state machines
  • hierarchy of subsystems
  • reusable component definitions with explicit interfaces
  • explicit visible connections between the interface elements of the components
• building a reactive real-time system from parts that are built using more information processing oriented technologies:
  • OO, e.g. UML
  • C
  • C++
  • other languages that can be called from C (or C++)
• building an easy-to-interface subsystem to be run under a real-time operating system
• building a limited stand-alone system

ReaGeniX Programmer does ...

• implement the state behaviour drawn as state transition diagrams
• implement the architecture drawn as subcomponents and communication paths between them
• write ANSI-C
• take care of concurrency in all levels of hierarchy (non-pre-emptive)
• take care of timing and all communication between components
• produce re-entrant modules of standard coding style
• produce optimized high-speed code

---

Use the ReaGeniX Programmer to ...

• get early feedback of the validity of the system concept
• improve maintainability of the system
• produce and use reusable software and design components
• get the system up and running earlier

Diagrams are drawn using a Visio® tool

The first application was in space communications

Benefits of the ReaGeniX Programmer

• less work in design and coding - the coding effort of concurrency, timing and asynchronous communication is removed
• improves the quality of the code - the errors are found easily in unit testing
• improves maintainability - explicit interfaces reduce side effects of changes
• improves the quality of the documentation - maintenance of software on graphical document level

Features of the ReaGeniX Visual Language

modelling principles

• diagrams define active "component" classes to be instantiated and interconnected in higher levels of hierarchy (analogy of electronics design)
• high modularity
  • all inter-component communication or data access takes place through ports of strictly defined interfaces
  • no names of communication partners are available for (or needed by) the components
• communication between component instances
  • asynchronous data and event based
  • continuous values and discrete messages
  • control connections to switch another component on or off
• C data types (or C++ classes) are used
• indexing for repeated structures

architecture diagrams

• branching of connections for broadcasting
• merging of connections
• static architecture
  • allows fast and compact implementation
• extended state variables (data stores, private attributes) available in each level of hierarchy

state-transition diagrams

• C (or C++) is used in actions of the state transitions
• several possibilities for transition conditions
  • events
  • events with guarding boolean expressions
  • boolean expressions to allow a transition to fire immediately when the preceding state is entered
• nontrivial computations are preferably done in functions (or methods) called from the actions
  • this is the place for the code developed by other methods: hand written, generated by OO tools, etc.
• number of timers is not limited by the run-time environment
