Automotive SoCs implement 3D graphics clusters

The first member of SoC in the R-Car family have been announced by Renesas. They can be used in 3D instrument cluster systems and provide a migration path as more automotive systems are expected to shift to 3D graphics instrument cluster systems in the near future.

The R-Car Family of SoCs implements high-functionality HMI for high-end automotive cockpit systems. There is also gauge control support through the RH850/D1x microcontrollers for entry-level and mid-range automotive systems.

3D graphics cluster systems can be developed by co-operating with Renesas partners. Instrument cluster systems require a rapid start-up so that, for instance, immediately after the driver opens the driver’s side door, or at the same time accessories are starting up, the system can instantly display the screen or output audio run at high speed. Partner companies participating in the R-Car ecosystem, provide solutions that support high-speed system start-up, rapid display of meter and gauge screens, and audio output.

To implement high-reliability systems, the SoC supports the ISO 26262 standard for automotive functional safety. A Functional Safety Support Program implements functionally safe systems.

To prevent hacking, the RH850 32-bit MCU includes hardware security functions that can be combined with the R-Car D1.

The SoC includes the variety of communications interfaces required in an instrument cluster system, including Ethernet AVB for connection with navigation systems, USB to connect with smartphones, and CAN-FD to connect with automotive infotainment systems, it supports superlative system flexibility and ease of design.

Development assets from the 2D graphics cluster RH850/D1x can be applied. The RH850/D1M group of MCUs can implement both gauge control and 2D graphics display with a single chip and is already used in a range of cars. Since the R-Car D1 SoC includes the same 2D graphics system as that used in the RH850/D1M, system manufacturers can make use of these 2D graphics development assets, and develop 3D graphics systems for the R-Car D1. If gauge control is required, system manufacturers can also combine the R-Car D1 with the RH850/D1M to implement such systems.

Mass production is scheduled to begin in March 2017.
