These slides present the summary of the BIP offer. BIP is a framework for the development and analysis of critical real-time embedded systems.

1. BIP framework Development and analysis of critical real-time embedded systems

2. Target applications Software control of critical systems… Transport (automotive, avionics, etc.) Robotics Healthcare …must satisfy safety requirements Deadlock-freedom BIP is your solution For the analysis of existing applications For the development of correct by construction applications

3. Harness the concurrency Concurrent systems are hard to design and verify Cause : state space explosion Solution: compositional approach… Sequential atomic components Glue – coordination without additional behavior …with BIP Synthesis of the coordination layer Correctness by construction Independent analysis of components and glue

4. Formal language for component-based modeling Coordination language for C Tools for analysis and transformation Safety properties analysis (e.g. deadlock-freedom with DFinder) Performance optimization with respect to architectural constraints Functional and non-functional analysis Compilation chain Parser, code generation Simulation engine Execution on multi-core and distributed architectures What is BIP?

5. Expressivity Direct expression of any type of coordination without additional behavior Construction by integration of elementary functions Generality Compatible with many programming models Synchronous dataflow Shared memory Message passing Correctness by construction Glue synthesis Source-to-source transformations Performance optimization with respect to architectural constraints Automatic generation of distributed models Why use BIP?

7. Modeling and analysis D-Finder – a BIP tool for the analysis of safety properties satisfaction Compositional and incremental deadlock detection High performance even on models that other tools fail to analyze Red curve in the graph shows D-Finder analysis time for the Dining philosophers problem

8. Componentization Autonomous robot Dala developed at LAAS (Toulouse) http://homepages.laas.fr/matthieu/robots/dala.shtml Control layer: ~300 000 lines of initial source code Componentization Verification of safety properties Code generation The MARAE project awarded by FNRAE Fondation de Recherche pour l’Aéronautique et l’Espace Foundation for Research in Aeronautics and Space EADS, Safran, Thalès, … http://www.ujf-grenoble.fr/1274965794187/0/fiche___actualite/

9. Benefits Analysis V&V cost reduction Qualification and certification assistance Development Development methodology supported by theoretical results Shorter time-to-market Development effort focused on business specific challenges Componentization Simplification and quality improvement of the existing code base Component re-use throughout the company Simplified coordination with outside partners
