Concurrent Scheduling of Event-B Models
Event-B is a refinement-based formal method that has been shown to be useful in developing concurrent and distributed programs. Large models can be decomposed into sub-models that can be refined semi-independently and executed in parallel. In this paper, we show how to introduce explicit control flow for the concurrent sub-models in the form of event schedules. We explore how schedules can be d...
متن کاملCompositional scheduling analysis using standard event models
The ever increasing advances in silicon and communication technology allow the integration of increasing functionality in digital embedded systems, ranging from mobile phones through multimedia home platforms to automotive control networks. Embedded system designers have to cope with this increasing system complexity whilst still building competitive systems to survive the market pressure, thus...
متن کاملScheduling of Compute-Intensive Code Generated from Event-B Models: An Empirical Efficiency Study
Event-B is a tool-supported speci cation language that can be used e.g. for modelling of concurrent programs. This calls for code generation and a means of executing the resulting code. One approach is to preserve the original event-based nature of the model and use a runtime scheduler and message passing to execute the translated events on di erent computational nodes. In this paper, we consid...
متن کاملAutomating Verification of Event-B Models
Event-B is one of more popular notations for model-based, proof driven specification. It offers a fairly high-level mathematical language based on FOL and ZF set theory and an economical yet expressive modelling notation. Model correctness is established by discharging proving a number conjectures constructed via a syntactic instantiation of schematic conditions. A large proportion of provable ...
متن کاملThe Composition of Event-B Models
The transition from classical B [2] to the Event-B language and method [3] has seen the removal of some forms of model structuring and composition, with the intention of reinventing them in future. This work contributes to that reinvention. Inspired by a proposed method for state-based decomposition and refinement [5] of an Event-B model, we propose a familiar parallel event composition (over d...
