Object-oriented enhancement of real-time software using a heterogeneous re-engineering approach

A technique for incremental modernisation and enhancement of an existing procedural real-time software to an object-oriented one is presented. The incremental enhancement enables the real-time system designer to make use of the advantages of object-oriented paradigm: the resulting re-engineered software is more maintainable, reusable and configurable. In this approach, the object structure and additional new features can be validated interactively and iteratively using heterogeneous graphical animation. Different parts of the system may present different modelling levels during the enhancement, thus making the incremental process of software partitioning, object derivation and object design easier to manage
