Techniques for inter-application communication and handling of I/O devices in an Integrated Modular Avionics (IMA) system enable the integration of multiple applications (B) while maintaining strong spatial and temporal partitioning between application software modules or partitioned applications (P1, P2). The integration of application modules is simplified by abstracting the desired application interactions in a manner similar to device access. Such abstraction facilitates the integration of previously developed applications as well as new applications. The invention requires the least support from the operating system and minimizes the dependency of the integrated environment on application characteristics.

L'invention se rapporte à des techniques de communication inter-applications et de gestion des dispositifs d'E/S dans un système avionique modulaire intégré (IMA), qui permettent l'intégration de multiples applications (B) et maintiennent simultanément un partitionnement spatial et temporel fort entre des modules logiciels d'applications ou des applications partitionnées (P1, P2). L'intégration de modules d'applications est simplifiée du fait que les interactions souhaitées entre applications sont conceptualisées d'une manière similaire à l'accès aux dispositifs. Une telle abstraction facilite l'intégration d'applications développées antérieurement ainsi que celle d'applications nouvelles. L'invention ne nécessite qu'un faible soutien du système d'exploitation et elle minimise la dépendance de l'environnement intégré par rapport aux caractéristiques des applications.
