Real Time Applications increasingly require a Graphical User Interface (GUI). Although the market asks for a common known appearance in terms of look and feel, real time requirements for interfacing to graphics are definitely different. It's the internal way in which a real time process communicates with a GUI - and vice versa - that determines whether the complete system runs efficiently or not.

Hard and software structures of embedded applications are manifold: There are small systems without any direct user interface - perhaps connected to a central control system; there are large and powerful systems with their own complex user interface and there is a broad range of units that require remote maintenance; and there is a whole range of considerations in between these.

XiSys Software GmbH has therefore decided to offer a well-structured and portable GUI, that fulfills all the above requirements plus more, like its own desktop manager. XiSys's objective is to reduce development time, to minimize the programmer's involvement in handling GUI internals, and to maximize the flexibility of embedded applications.
