19 Security and Safety via Separation Safety: Protecting the world from the device Security: Protecting the device from the world Mixed criticality: Protecting of security or safety critical parts of the device from other parts of the device ISO requires freedom from interference. If two systems can interfere with each other, they must be certified to the highest ASIL level of the two. Secure separation aims to eliminate such interference. 19

20 Use Case 1: Physical Separation aka AMP 20

21 What the system looks like today Graphics or Web Real Time App A9 A9 Multicore Device running one Operating System Migrating to multicore device for the next generation or project Need to consolidate applications that require real time and determinism with applications requiring networking or graphics services Addressing performance constrains of existing design 21

22 What the system will look like Graphics or Web Real Time App A9 A9 or M4 Multicore Device running multiple Operating Systems Single user interface for Configure, Edit, Debug, Optimize work Framework to configure, boot, execute and communicate across cores and Operating Systems Take full advantage of the underlying silicony goodness J 22

23 How this could be accomplished Sourcery CodeBench IDE Core Lifecycle Management Floor 5 Room 304 Patient Name: Jan Facility: Clinic User Applications Webserver Qt HMI rpmsg virtio Mentor Embedded Remote Firmware Patient Sensor Data Acquisition Application Mentor Embedded Multicore Framework remoteproc Nucleus rpmsg virtio ARM Cortex -A9 IPC Freescale i.mx 6SoloX ARM Cortex -M4 23

24 Use Case 2: Separation using Software Enforcement 24

25 What the system looks like today Cluster App Infotainment App ECU App OS OS Autosar SoC SoC SoC Multiple boards running various Operating Systems and dedicated applications Migrating to multicore device for the next generation or project Need to consolidate applications that require real time with Must share displays and other resources 25

26 What the system will look like Cluster App Infotainment App ECU App Autosar A15 Hypervisor A15 M4 Consolidation to a single Heterogeneous Multicore SoC running multiple Operating Systems and Applications Virtualizing GPU to either control multiple displays per application or layer multiple applications on a single display (1:1, 1:N, N:1) Framework to configure, boot, execute and communicate across domains in safe and reliable matter 26

27 How this could be accomplished Infotainment Display Cluster Display FPD-Link Display 12 (1280x480 ) FPD-Link Touch Display 10 (1280x800 ) BusMaster CAN Vehicle Simulator USB 2CAN CAN BUS AUTOSAR & CAN stack on M4 IVI AXSB J6 27 Nucleus Hypervisor (2xA15) + GPU sharing

28 Use Case 3: Separation using Hardware enforcement 28

29 What the system looks like today App 1 App 2 App 1 App 2 A9 A9 A9 One or more cores running applications of various security or robustness levels Migrating to multicore or more powerful device for the next project Need to consolidate applications that require secure and non secure apps 29

30 What the system will look like Secure App nonsecure App Secure App nonsecure App A9 A9 A9 One or more cores running applications of various security or robustness levels Migrating to multicore or more powerful device for the next project Need to consolidate applications that require secure and non secure apps 30

31 How this could be accomplished Secure App nonsecure App Secure App nonsecure App Nucleus Data Control Nucleus or Nucleus Data Control Nucleus or Hardware Separation Hardware Separation A9 A9 A9 Using the Hardware Separation features of ARM architecture to isolate secure or robust applications from the rest of the system Control only flows from Secure World to Normal World Data could flow either way 31

32 How this could be accomplished: Example Non-certified Complex Instrument Logic Certified Safe Instrument Logic Single Core Complex Graphics Render Safe Graphics Render Safe Graphics Driver draws content to separate graphics plane managed by safe driver Dual Core planes blended in hardware, also managed by safe driver 32
