Download or read book Embedded Software Development for Safety Critical Systems written by Chris Hobbs and published by CRC Press. This book was released on 2015-10-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety-critical devices, whether medical, automotive, or industrial, are increasingly dependent on the correct operation of sophisticated software. Many standards have appeared in the last decade on how such systems should be designed and built. Developers, who previously only had to know how to program devices for their industry, must now understand remarkably esoteric development practices and be prepared to justify their work to external auditors. Embedded Software Development for Safety-Critical Systems discusses the development of safety-critical systems under the following standards: IEC 61508; ISO 26262; EN 50128; and IEC 62304. It details the advantages and disadvantages of many architectural and design practices recommended in the standards, ranging from replication and diversification, through anomaly detection to the so-called "safety bag" systems. Reviewing the use of open-source components in safety-critical systems, this book has evolved from a course text used by QNX Software Systems for a training module on building embedded software for safety-critical devices, including medical devices, railway systems, industrial systems, and driver assistance devices in cars. Although the book describes open-source tools for the most part, it also provides enough information for you to seek out commercial vendors if that’s the route you decide to pursue. All of the techniques described in this book may be further explored through hundreds of learned articles. In order to provide you with a way in, the author supplies references he has found helpful as a working software developer. Most of these references are available to download for free.

Download or read book Performance of Time Critical Embedded Systems under the Influence of Errors and Error Handling Protocols written by Philip Axer and published by Cuvillier Verlag. This book was released on 2016-02-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: As for the entire embedded-systems domain, the complexity of safety-critical systems is growing rapidly. Additionally, the rate of errors in such devices also increases for instance due to silicon shrinking. Hence, error-free operation under in-specification operating conditions cannot be assumed for next-generation safety-critical devices. As a rule of thumb the key design parameters for such systems performance, price and reliability are almost always contradicting design goals. This work addresses the related design space, highlights the challenges and discusses the trade-offs. Of unique interest is the reliability under real-time aspects. Naturally, there are error-handling protocols, error-correcting codes, and modular redundancy available. However, the effect of errors always has an influence on system timing. Even if an error is handled and corrected, it remains unclear under which situations timing requirements are met. This leads to the absurd situation that a device such as an advanced driver assistance system produces correct data even under errors but fails to deliver service because hard deadlines are missed. We present the ASTEROID architecture as a next-generation high-performance, real-time platform which addresses reliability and thus safety aspects. ASTEROID differs from other MPSoC platforms in its cross-layer error handling approach. The hardware implements the bare minimum to support the operating system with support for redundant computing, allowing the software to flexibly schedule tasks for redundant or regular execution. This architecture was joint work between TU Braunschweig and TU Dresden. In this work, we present the hardware architecture and discuss the real-time performance under errors in a compositional way. Therefore, we consider errors in communication (be it on-chip as well as off-chip) and errors in the processing core itself. The scientific contributions are first to extend compositional performance analysis (CPA) also by covering error effects, second to cover end-to-end error protocols with CPA, third to provide execution models and analysis for redundant execution and finally to bound the likelihood of timing violations in communication and computation under a given error model. Sowohl eingebettete Systeme im Allgemeinen, als auch sicherheitskritische Systeme im Speziellen werden zunehmend komplexer. Hinzu kommt, dass aufgrund der Verkleinerung der Strukturbreite moderner Halbleiterprozesse die transiente Fehlerrate deutlich ansteigt. Daher kann nicht von einem fehlerfreien Betrieb von zukünftigen eingebetteten, sicherheitskritischen Systemen unter nominalen Bedingungen ausgegangen werden. Als Faustregel kann man zusammenfassen, dass die Schlüsselparameter im Entwurfsraum Performance, Preis und Zuverlässigkeit so gut wie immer widersprüchliche Entwurfsziele sind. Diese Arbeit zielt auf diesen Entwurfsraum ab, zeigt die Herausforderungen und diskutiert die Trade-Offs. Von besonderem Interesse ist die Zuverlässigkeit unter Echzeitaspekten. Selbstverständlich gibt es Fehlerbehandlungsprotokolle, Fehlercodes und modulare Redundanz. Allerdings hat die Korrektur von Fehlern immer einen gewissen Einfluss auf das Zeitverhalten des gesamten Systems. Selbst, wenn ein Fehler korrigiert werden konnte, ist unklar, unter welchen Situationen das Zeitverhalten eingehalten wird. Dies kann zu der absurden Situation führen, dass ein Fehler in einem Fahrerassistenzsystem korrigiert werden kann, dennoch aber das Verpassen einer Deadline zu einem Systemfehler führt. In dieser Arbeit stellen wir die ASTEROID Plattform vor, die im Rahmen einer Kooperation der TU Braunschweig mit der TU Dresden entstanden ist. Diese Plattform ist speziell im Hinblick auf Echtzeitaspekte, Performance, Zuverlässigkeit und damit einhergehend Sicherheit entworfen worden. ASTEROID unterscheidet sich von anderen MPSoC Plattformen durch seinen Cross-Layer Fehlerbehandlungsansatz. Die eigentliche Hardwareplattform implementiert nur das absolute Minimum an Fehlertoleranz, um das darüber geschaltete Betriebssystem zu unterstützen. Dieses übernimmt dann die eigentliche Redundanz und erlaubt damit eine flexible Mischung von redundanten und nicht-redundanten Anwendungen. In dieser Arbeit wird die Plattform in Bezug auf die Echtzeitperformanz unter Fehlern in einer kompositionellen Weise untersucht. Dafür werden Fehlereffekte in der on-chip und off-chip Kommunikation sowie Fehler im eigentlichen Rechenkern selbst betrachtet. Der wissenschaftliche Beitrag dieser Arbeit liegt zum einen in einer generalisierten kompositionellen Performanzanalyse, die zudem Fehlereffekte berücksichtigt. Zum Anderen werden Ende-zu-Ende Protokolle und redundante Anwendungen modelliert und in Bezug auf ihre Echtzeitfähigkeit untersucht. Für viele der genutzten Verfahren wird auch eine Zuverlässigkeitsabschätzung des Echtzeitverhaltens bei einem gegebenen Fehlermodell durchgeführt.

Download or read book Practical Embedded Security written by Timothy Stapko and published by Elsevier. This book was released on 2011-04-01 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great strides made over the past decade in the complexity and network functionality of embedded systems have significantly enhanced their attractiveness for use in critical applications such as medical devices and military communications. However, this expansion into critical areas has presented embedded engineers with a serious new problem: their designs are now being targeted by the same malicious attackers whose predations have plagued traditional systems for years. Rising concerns about data security in embedded devices are leading engineers to pay more attention to security assurance in their designs than ever before. This is particularly challenging due to embedded devices’ inherent resource constraints such as limited power and memory. Therefore, traditional security solutions must be customized to fit their profile, and entirely new security concepts must be explored. However, there are few resources available to help engineers understand how to implement security measures within the unique embedded context. This new book from embedded security expert Timothy Stapko is the first to provide engineers with a comprehensive guide to this pivotal topic. From a brief review of basic security concepts, through clear explanations of complex issues such as choosing the best cryptographic algorithms for embedded utilization, the reader is provided with all the information needed to successfully produce safe, secure embedded devices. The ONLY book dedicated to a comprehensive coverage of embedded security! Covers both hardware- and software-based embedded security solutions for preventing and dealing with attacks Application case studies support practical explanations of all key topics, including network protocols, wireless and cellular communications, languages (Java and C/++), compilers, web-based interfaces, cryptography, and an entire section on SSL
