Accelerates the time-to- deployment for challenging FAA RTCA DO-178C DAL A multi-core certification programs Certification: Multi-core systems use case Multi-core systems bring an additional layer of complexity in terms of system integration and certification. Beyond the technical aspects related to safe partitioning, avionics suppliers must also manage the business concerns related to pulling in applications from various providers. These applications must all share the same processor, but they often times can be certified at different certification design

assurance levels (DAL), according to their impact on mission safety. Another critical issue for avionics companies is shortening the development cycle and certification cost of adding features to software. For instance, if one application is updated, or another one added, this raises the question whether the whole system should go through a recertification process or if certification can be done only on the affected application. In VxWorks® 653 Multi-core Edition these platforms can run on different partitions. They can be updated and certified separately. Using robust partitioning and a qualified XML compiler, one partition can be updated and certified without affecting the rest of the system. This is extremely valuable when deploying applications at different

levels of safety criticality. Without a robust partitioning strategy all applications would have to be certified at system high – with robust partitioning each IMA application only needs to be only at its minimum DAL level. Investing in multiple recertification projects for the entire system at system high creates far higher cost and schedule risk for the avionics project. With the release of the certification evidence for VxWorks 653 Multi- Core Edition, Wind River is providing practical evidence of its premier certification of the multi-core solution for ARINC 653 IMA systems, allowing avionics companies to lower project risks for multi-core systems certification.
