Solving Multicore Processors CAST-32A Avionics Certification Challenges

Certification authorities and industry suppliers have invested in numerous studies and discussions over recent years to identify the issues multicore processors pose for safety critical systems. Formalized positions of these efforts are the FAA CAST-32A Position Papers. The crux of this paper (regarding software) focuses on bounding and controlling the interference patterns that exists when processor cores share resources. Unless interference patterns are addressed, real-time operations can be erratic and worse case execution (WCE) times can be longer than in a single core system. This 30 minute webinar will outline CAST-32A from a software perspective, highlighting the challenges of implementing multicore processors for any avionics developer and how to solve them.
