Transparent Environment for Replicated Ravenscar Applications

Abstract. This paper proposes an environment intended for the development of fault-tolerant real-time Ada 95 applications conforming to the Ravenscar profile. This environment is based on the transparent replication of application components, and it provides a set of generic task interaction objects, which are used as the basic building blocks of the supported applications. These objects provide the usual task interaction mechanisms used in hard real-time applications, and allow applications to be developed without considering replication and distribution issues.
