Green Hills Software: Applying Multicore Avionics Software Architectures to Automotive and Industrial Safety/Security-Critical Applications

About This Training

Using multicore Arm processors in safety- and security-critical automotive systems such as automated driving and e-Cockpit has many attractions. However, for some applications, presents challenges for determinism and safety due to substantial variations in worst-case execution time resulting from contention for access to shared processor resources. For these critical systems, effects of multicore interference could be catastrophic.

A general and robust solution is described, based on a microkernel operating system leveraging Cortex-A architectural features. Less deterministic approaches are compared. Primary benefits are summarized, including how changes to applications do not require retesting every application in the system and the positive effects of time and space partitioning to reduce development, testing, verification and certification times of multicore safety-critical systems.
