Creating Software Separation for Mixed Criticality Systems Vortragssprache Englisch

The introduction of powerful embedded processors is driving system consolidation for safety critical devices. While software is becoming more complex as features are merged onto a single system-on-chip (SoC), device manufacturers are facing increased scrutiny from regulatory agencies over the safety of their devices. In a safe system, the safety critical software must have guaranteed and predictable access to compute over other system resources. The intermixture of safety critical and non-safety critical software is possible on today’s modern processors, but adds to the overall design complexity. In order for guaranteed resource access by the safety application there must be isolation from non-safety code to prevent any interference; and thus several key areas must be considered including memory partitioning and managing access to kernel resources. This session discusses how to use a process model and Arm TrustZone for space domain partitioning to cost efficiently isolate critical code from non-critical code for devices requiring IEC 61508 and IEC 62304 safety certification.
