3. Agenda
1. Mysterious Tier-1 Customer
2. Cutting-edge hardware
3. The hypervisor we deserved
4. Role of Automotive Grade Linux
5. Android as AGL “alternative”
6. AUTOSAR – the misunderstood standard

4. Mysterious Tier-1 Customer
1. Leading European Tier 1 and supplier of in-car electronics
2. Cutting-edge HW based on Qualcomm Snapdragon SoC
3. Very early and cutting-edgy peripherals (SerDes/HDBaseT/etc)
4. Sweet (almost) ready-to-use BSP (QNX/AGL/Android)
5. Various sub-projects
6. Quite challenging tasks

5. System-On-
Chip

6. System-On-Chip
• Qualcomm Snapdragon Automotive
• 8 cores (4 Silver, 3 Gold, 1 Gold+) with 2.2…2.7GHz/core
• Adreno GPU
• UFS (up to 265Gb)
• LPDDR4 (up to 32Gb)
• Qualcomm Universal Peripheral (supports I2C/SPI/UART)
• DSI/DP (up to 4K)
• CSI (FHD@60fps)
• Audio (TDM8-32/I2S)
• BT/WLAN/USB
• Ethernet

7. A2B

8. A2B
A2B is high bandwidth audio bus which can:
• Be controlled via simple I2C interface
• Transport I2S/TDM data and I2C control information
• Connect multiple devices via single UTP cable (up to 15 meters)

9. FPD-Link
SerDes

10. FPD-Link SerDes
• Up to 27Gbps over Dual Channels
• Single coax cable with Power-over-Coax (up to 10 meters)
• Interference free
• Ready for ADAS and infotainment displays:
• 4K@60Hz displays
• 7..8MP@40fps imagers

11. HDBaseT

12. HDBaseT
• Simultaneously tunneling multiple streams of HD
video/audio/data/USB/controls/power
• Transmission over a single 15m UTP cable
• Near-zero latency (less than 10 µsec) for real-time applications
• Highly robust solution with adaptive mechanism to deal with EMC,
cable aging, temperature changes etc.
• Support for several applications, including telematics and
infotainment, ADAS, smart phone connectivity, USB extensions
and more

13. QNX/Hypervisor

14. QNX
• Microkernel architecture
• Hard real time RTOS
• Safe by design (ISO 26262 – ASIL D)
• Resource manager support (user space drivers)
• Is used for instrument cluster and HUD
• GL role:
• Video framework development
• Voltage monitoring system
• Power supply/wake up drivers
• Production diagnosis
• and so on…

15. QNX Hypervisor
• Type 1 (run on the HW directly)
• Exclusive or shared access to HW between guests
• Small overhead compared to native environment
• Security certification (IEC 61508 SIL 3)
• Easily scalable

16. Automotive
Grade Linux

17. Automotive Grade Linux
• AGL UCB is ready for bare-metal QC eval board
• Build with Yocto
• Requires bring-up on Customer board (multiple variants)
• GL role:
• Basic hardware bring-up and verification
• Design Verification testing (mechanical/termal/performance)

18. Android

19. Android
• Automotive HAL Inside™
• Is used as Infotainment VM for:
• Head Unit
• Rear-Seat Entertainment
• Video/audio
• Network and connectivity (WLAN/BT/USB)
• Apple CarPlay
• GL role:
• Shared resources (I2C/DP/WLAN/BT)

20. AUTOSAR

21. AUTOSAR
• AUTomotive Open System ARchitecture is an open and standardized
automotive software architecture
• Safe by design (ISO 26262 – ASIL D)
• Improve software quality and reduce costs by re-use
• Re-useability of:
• functions across carlines and across OEM boundaries
• development methods and tools
• basic software
• Role of GL:
• Bring-ups
• Features implementation
• Testing and integration
