Delivering 3D Graphics to Entry-Class Vehicles

William Wong, Technology Editor

The Renesas R-Car D3 system will allow developers to share 3D graphic assets for high-performance R-Car H3 and R-Car M3 chips.

The Renesas R-Car D3 system delivers 3D graphics and high-end audio support for entry-class vehicles that have usually come with 3D graphic instrument clusters. It will allow developers to share 3D graphic assets for high-performance R-Car H3 and R-Car M3 chips found in mid-range and high-end automotive vehicles. 3D graphics provides improved information presentation to drivers and passengers.

Renesas’ R-Car D3 system can drive multiple displays delivering 3D content and high-performance audio.

“For more than a decade, automotive OEMs and Tier 1s have relied on BlackBerry QNX to deliver world-class software solutions for infotainment, telematics, and instrument cluster systems,” says Grant Courville, senior director of product management at BlackBerry QNX. “The combination of the new R-Car D3 SoC and BlackBerry’s ISO 26262 ASIL B-certified QNX Platform for Instrument Clusters will enable our customers to confidently deliver state-of-the-art, safety-certified digital clusters rapidly to the market.”

The R-Car D3 is built around a 64-bit, Arm Cortex-A53. Imagination Technologies provides the PowerVR Series8XE 3D graphics cores. The system supports a pair of LVDS outputs plus a video input channel to support features like a backup camera. The Ethernet interface supports AVB 1.0 and the CAN controller supports CAN-FD. There is also a Media Local Bus (MLB) interface. Storage support includes a NAND flash interface, SD card support, and USB 2.0 with MAC and PHY on-board. DRAM can be DDR3 or DDR3L.

“The safe and secure INTEGRITY real-time operating system is widely used for automotive in-vehicle infotainment and instrument clusters in productions programs around the globe. Our support for the R-Car D3 builds on years of successful partnership with Renesas and their other R-Car devices, providing the customer with certified automotive safety, time-savings development tools, and optional virtualization for Linux,” says Matt Slager, director of Asia-Pacific business development at Green Hills Software. “We see this third-generation R-Car D3 as a valuable addition to the R-Car Family of SoCs, enabling customers to easily migrate and reuse existing R-Car and INTEGRITY software assets for faster time to market for their next-generation integrated cockpit designs.”

The 19-mm by 19-mm FCBGA chip is designed to reduce the system bill-of-materials (BOM). It can be placed on low-cost, four-layer printed circuit boards (PCBs). This allows systems to be delivered for costs comparable to competing 2D graphics-based systems. The R-Car D3 is supported by a range of software including operating systems such as Linux, QNX Neutrino RTOS and Green Hills INTEGRITY.
