Embedded Systems Design Using Event-B Theories

Low-cost embedded systems design using Statecharts

The main goal of the work here presented is to support the whole development cycle of low-cost embedded systems modelled by Statecharts, from specification to implementation. Specific goals include automatically verification of proprieties and generation of executable code for low cost hardware platforms, starting with the Statechart high-level specification of the reactive system. Micro-contro...

Incremental Design of Distributed Systems with Event-B

It is shown how Event-B can be use to model and reason about distributed systems from a high-level global view down to a detailed distributed architectural view. It is shown how refinement and decomposition can be used to introduce distribution of state and control and to introduce message passing between components. Distribution is treated as a special case of concurrency. Techniques are prese...

Event Pattern Detection for Embedded Systems

Events play an important role in many computer systems, from small reactive embedded applications to large distributed systems. Many applications react to events generated by a graphical user interface or by external sensors that monitor the system environment, and other systems use events for communication and synchronisation between independent subsystems. In some applications, however, indiv...

Rigorous Design of Fault-Tolerant Transactions for Replicated Database Systems Using Event B

System availability is improved by the replication of data objects in a distributed database system. However, during updates, the complexity of keeping replicas identical arises due to failures of sites and race conditions among conflicting transactions. Fault tolerance and reliability are key issues to be addressed in the design and architecture of these systems. Event B is a formal technique ...
