AURIX™ SMP Safety Platform

Example for an AURIX™ SMP safety platform

This solution shall meet the following main goals:

  • Symmetric Multi-Processing (SMP)  -  We want to use a single RTOS for handling the tasks on all cores.
  • Pre-Certified RTOS  -  We want to use a pre-certified real-time operating system.
  • Online Self-Tests  -  We want to use online hardware self-tests as required by the AURIX™ safety manual.

    • Furthermore, the solution shall meet some high-level business goals:

  • Space Protection Mechanism  -  We want to use mixed safety capabilities on all cores.
  • LTS for complete Platform  -  We want to have a long-term supported (LTS) safety platform.

    • Building Blocks

    Flexible Safety RTOS

    The Flexible Safety RTOS provides a deterministic hard real-time scheduling and is responsible for:

  • Scheduling application tasks
  • Managing task separation
  • Task synchronization services
  • Task communication services

    • Component Tailoring

    With the service Component Tailoring, the system is enhanced with the features:

  • Symmetric Multi-Processing
  • Static Task Affinity
  • Inter-Core Communication

    • Infineon SafeTLib

    The Infineon SafeTLib provides services for checking the hardware during application execution:

  • Core and Memory Checks
  • Peripheral and Register Checks
  • Supports Safety Watchdog
