AMP OSes, Single SMP OS or Hypervisor based solution, how to choose in a multi-core Safety Certification context?

Olivier Charrier

Functional Safety Specialist, Wind River

Single-core processors are being replaced by multi-core System-on-Chip devices, which have the potential to cause interference between these multiple cores.

Multi-core interferences can have a significant impact on functional safety. The avionics sector has been the first market to address multi-core interference with the definition of additional objectives to be addressed for Safety Certification in position papers like CAST-32A now superseded by FAA AC (upcoming) / EASA AMC 20-193.

But when it goes to the OS used to host applications in such environment, which kind to choose?

In this presentation we will review some of the key aspects to be taken into account.
