VxWorks 653, Cert, and MILS Certified Platforms

Proven in the most challenging safety- and security-critical applications, VxWorks® makes it easier and more cost-effective for technology suppliers to meet the stringent certification requirements of ARINC 653, DO-178C, ED-12C, and FACE standards of aerospace, defense, transportation, and other industries.

Wind River VxWorks 653 Platform

VxWorks 653 is the leader in commercial off-the-shelf (COTS) ARINC 653 real-time operating environments. More than 200 customers have used VxWorks 653 in over 400 programs in over 80 civilian and military aircraft, including the Boeing 787 Dreamliner, the Airbus A400M, and the Northrop Grumman UH-60V Blackhawk avionics upgrade. The robust time-and-space safety partitioning and virtualization capabilities of VxWorks 653 are proven in certified mission-critical avionics systems, making it an excellent choice for critical industrial and transportation systems and devices.

VxWorks 653 is the first RTOS to be certified conformant to the Future Airborne Capabilities Environment (FACE™) Technical Standard managed by The Open Group. VxWorks 653 Platform 2.5 is certified conformant to the FACE Technical Standard Operating System Segment (OSS) Safety Base Profile supporting all ARINC 653 and POSIX capabilities required by the FACE Conformance Test Suite.

VxWorks 653 3.0 Multi-core Edition adds support for the latest multi-core processors and provides unmodified guest OS virtualization support for ARINC 653, VxWorks, Linux, and Windows on a shared multi-core processor. It delivers the following additional benefits:

High performance with lower development costs

  • Supports a variety of guest operating systems through a multi-core-enabled scheduler, allowing applications to run in parallel to increase compute capacity and ensure space and time partitioning for each core
  • Delivers high performance and low jitter through a two-level virtual machine architecture
  • Scales up to 255 partitions
  • Can simultaneously support multiple safety levels

Easy portability and less costly upgrades

Supports a wide variety of specifications, standards and APIs:

  • FACE Technical Standard 2.0
  • FACE Technical Standard 2.1
  • ARINC 653 APEX, VxWorks, POSIX®, Ada, Java, C and C++

Streamlined development for faster build cycles

  • Uses DO-297 role-based development for clear separation of platform supplier, application developers, and system integrator
  • Includes Wind River Workbench, an Eclipse-based development suite that supports integration with a wide variety of software tools

Simplified DO-178B/C platform certification

  • DO-297 role separation via DO-178- and DO-330-qualified development and verification tools
  • Complete application independence with separate build, debug, test, certification, and recertification of applications
  • All DO-178C and ED-12C DAL A evidence with more than 70,000 files, hyperlinked for easy traceability and examination, provided in a sealed DVD
  • Independent build process, reducing the impact of code changes across multiple development teams

Wind River VxWorks Cert Platform

Wind River VxWorks Cert Platform is a real-time operating system for safety-critical applications that require RTCA DO-178, EUROCAE ED-12, or IEC 61508 certification evidence in avionics, transportation, industrial automation, and medical device industries.

VxWorks Cert Platform delivers the following capabilities:

  • Certification to RTCA DO-178, Level A on numerous projects
  • IEC 61508 SIL2/3 certification on numerous projects
  • Optional certified Highly Reliable File System (DO-178, Level A)
  • Optional support for real-time processes (RTPs, on select versions)
  • Optional Wind River Certified Network Stack (TCP/UDP/IPv4/Multicast, DO-178 Level A and IEC 61508 SIL3)
  • Proven, robust VxWorks API
  • Support for PowerPC, Intel, and ARM® architectures
  • Wind River Workbench development suite

Wind River VxWorks MILS Platform

Wind River VxWorks MILS Platform is an optimal operating environment for systems with high security, high assurance, and high performance requirements such as multilevel secure systems (MLS) and cross-domain solutions (CDS).

VxWorks MILS Platform implements the Multiple Independent Levels of Security (MILS) system architecture that enables multiple software components with different security levels, or from different domains, to safely and securely share the same hardware platform, helping reduce development costs, as well as size, weight, and power requirements.
