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.
