RXF ( (Real-time eXecution Framework)

RXF (Real-time eXecution Framework) is the runtime interface between a UML model and an embedded target platform in IBM Rhapsody. It abstracts RTOS (Real-Time Operating Systems) and environment-specific details through adapters, allowing application models to remain portable across different embedded platforms. RXF provides libraries implementing UML constructs needed for generated C/C++ code, including execution on systems without an RTOS.
