Anatomy of a Multi-Display-Cockpit: Multicore SoC, hypervisor and Linux

September 12, 2018 // By Christoph Hammerschmidt
The multi-display cockpit from automotive supplier Parrot Faurecia reveals its inner workings: The cockpit module draws its computing power from an R-Car H3 multiprocessor SoC of the Japanese chip supplier Renesas. The Android operating system controls the data traffic, and the Coqos hypervisor from OpenSynergy ensures secure separation of the functions between the operating system and the hardware.

The module can simultaneously control the functions of the instrument clusters with safety-relevant Linux-based display elements as well as the Android-based infotainment (IVI) functions on a single R-Car H3 SoC. Coqos shares the R-Car H3 GPU between Android and Linux. This allows applications to be displayed on multiple displays and powerful, flexible cockpit systems to be implemented.

"OpenSynergy's hypervisor technology on the Renesas R-Car H3 platform ensures functional security and scalability for our infotainment systems," said Frederic Fonsalas, Director of Strategy at Parrot Faurecia Automotive. The multi-display cockpit controller with this technology will go into production at a European premium car manufacturer in 2019, says Parrot Faurecia.

The Coqos Hypervisor SDK takes full advantage of Renesas' advanced hardware and software virtualization. OpenSynergy's solution includes core features such as a shared display so that multiple virtual machines can flexibly and securely use different displays.
