To provide the embedded market with development environments and withembedded hardware for generating applications where high-reliability andtrustworthiness are built-in into the design as part of the developmentprocess.Trustworthy =Safety => dependability / physical qualitySecurity => freedom from malicious faults/ data theftUsability => intuitive and pleasant to use /emotionalPrivacy => your data is your ownTrustworthy = higher added valueApplication domains:Ultra low power embedded devicesDistributed sensing and controlMany/multicore devicesParallel supercomputingFault tolerant/ safety critical systems26-May-11 Altreonic NV From Deep Space to Deep Sea - 5 5. Growing need for trustworthy technology:Electronics + SW replacing mechanical partsBeing embedded everywhere: part of our lifeInitially mainly driven by safety:Lives at stakeHigh economic costdrive by wire (e.g. Flanders Drive ASIL project)Increasingly shifting to notion of TRUSTEssential question: how to develop trustworthyproducts in a cost-efficient way?26-May-11Altreonic NV From Deep Space to Deep Sea -6 6. Support the whole engineering process in a unifiedway from early requirements capturing till the finalapplication giving a push button high reliabilityexperience at a reduced life cycle costApply formalisation to tackle complexityApply Formal Methods to prove correctness=> GoedelWorks integrated development portalMaximising the commercial potential by applying itsown methodology and tools for the developing oftrustworthy controllers in volume.=> OpenComRTOS: trusted runtime layer=> StarFish: Altreonics customizable controllers26-May-11 Altreonic NV From Deep Space to Deep Sea - 7 7.
