Cutting-Edge Virtualization Technology from Wind River Supports Development of ARINC 653– Compliant Multi-core Systems at Lower Cost and Risk EVOLVE IMA SYSTEMS TO SUPPORT FURTHER DEVELOPMENT, CERTIFICATION, RETROFITS, AND UPGRADES THE CHALLENGE The global aviation industry is on the cusp of transformation. Aircraft manufacturers are facing a constant increase in demand for connectivity and capabilities that reduce pilot workload and increase situational awareness. To meet these new requirements, they adopt increasingly sophisticated innovations in products and services. The result of the increased capability of these systems is a corresponding increase in the amount of software deployed. How can manufacturers manage the costs of aircraft design and upgrade? How can they adhere to size, weight, and power (SWaP) and performance requirements when implementing new capabilities under existing regulations? THE APPROACH Reducing SWaP has been a primary driver for the adoption of integrated modular avionics (IMA) architectures. The IMA approach advocates the use of common computing platforms that host multiple applications concur- rently, reducing the number of platforms required in the aircraft compared to a federated architecture. IMA is based on two fundamental principles: spatial partitioning and tem- poral partitioning. This partitioning ensures that the individual applications do not interfere with or affect each other. The enforcement of these prin- ciples is achieved through the specific implementation of the IMA software architecture (time slot scheduling in the case of ARINC 653) and memory management unit (MMU)-enforced separation of partitions. Wind River ® Helix ™ Virtualization Platform can take multiple federated systems on an aircraft and consolidate them onto a single compute plat- form. This virtualization solution will allow a manufacturer to consolidate safety-critical and general-purpose applications onto a single safe, secure, and reliable platform. AVIONICS CHALLENGES • Affordability: High cost of aircraft design, development, certification, retrofit, and upgrade • Performance and standards: Meeting of strict regulatory con- straints when implementing new capabilities WIND RIVER SOLUTIONS • Wind River Helix Virtualization Platform: A real-time, embedded, Type 1 hypervisor that can man- age unmodified guest operating systems running in virtual machines, consolidating heterogeneous appli- cations for IMA systems • VxWorks: The world's leading RTOS, enabling deterministic applications scaling from very small compute packages • Wind River Linux: Industry-leading open source operating system for connecting, securing, and running embedded systems and applications • Wind River Simics: Software that allows developers to simulate anything, chip to system, and get the access, automation, and collabora- tion tools required for agile develop- ment practices • Wind River development tools: Powerful tools to save developers time and increase quality 1 AVIONICS USE CASE
