Third-Generation R-Car Automotive Computing Platform for the Autonomous-Driving Era

Evolutionary R-Car Features Improved Computing Performance and Automotive Functionality Safety Support

Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, has unveiled the third-generation R-Car, an automotive computing platform solution for driving safety support systems and in-vehicle infotainment systems. The new R-Car H3 System-on-Chip (SoC), the first member of the third-generation R-Car, delivers CPU performance, image recognition processing, ISO 26262 (ASIL-B) compliance, and a system in package (SiP) with external memory to enable a wide range of automotive applications.

The R-Car H3 realizes powerful automotive computing performance exceeding that of the predecessor R-Car H2. This enables system manufacturers to utilize the new R-Car H3 as an automotive computing platform to play a key role in the autonomous-driving era.

To make the new device ideal for driving safety support systems, the R-Car H3 provides cognitive computing capabilities, an enhanced computing performance that can process large volumes of information from vehicle sensors accurately in real-time, and enables system manufacturers to run applications that require complex processing, such as obstacle detection, driver status recognition, hazard prediction, and hazard avoidance. To further accelerate the driving safety support systems, the R-Car H3 also conforms to the ISO 26262 (ASIL-B) functionality safety for automotive.

Furthermore, in in-vehicle infotainment systems, the need for connectivity between various systems and services such as smartphones and cloud services is growing. These have led to a significant increase in the volume of data transmitted from outside the system. Therefore, there is a demand for human-machine interface (HMI) computing to process these large amounts of data accurately in real-time. The outstanding performance power of the R-Car H3 makes excellent graphics design possible to realize advanced applications and rich HMI.

The R-Car H3 is an automotive computing platform ideal for the autonomous-driving era with significantly improved cognitive computing and HMI computing capabilities for advanced driving support systems as well as in-vehicle infotainment systems.

Key features of the new R-Car H3:

  • (1) Support for a wide range of applications as an automotive computing platform

    To enable system manufacturers to utilize the R-Car H3 as an automotive computing platform, the new device realizes powerful automotive computing performance exceeding that of the predecessor R-Car H2.To process large amounts of information accurately in real-time, the R-Car H3 is built around the ARM® Cortex®-A57/A53 cores, employing the newest 64-bit CPU core architecture from ARM. It achieves processing performance of 40,000 DMIPS (Dhrystone million instructions per second (Note 1)) for enhanced processing power. The R-Car H3 also features the PowerVR™ GX6650 as the 3-D graphics engine to deliver reliable information to drivers at the right timing. Based on the latest architecture from Imagination Technologies, it delivers approximately three times the shader calculation (Note 2) processing performance of the R-Car H2.
    The on-chip IMP-X5 parallel programmable engine offers advanced image recognition technology in addition to the CPU and GPU. Exclusive to Renesas, the IMP-X5 is a recognition engine that is optimized for interoperation with the CPU. It delivers four times the recognition performance of the earlier IMP-X4 image recognition engine, embedded in the second-generation R-Car family.
    The R-Car H3 is the first automotive SoC in the world to adopt the 16nm process. By realizing this high performance as well as compliance with the ISO26262 (ASIL-B) standard for automotive functional safety, the R-Car H3 can be used as an automotive computing platform that supports a wide range of applications, including advanced driving safety support systems and in-vehicle infotainment systems.
  • (2) Improved system level performance based on the results of rich in-vehicle infotainment systems

    As the market leader (Note 3) for worldwide in-vehicle infotainment SoC, Renesas has a surpassing system performance based on passed results. Especially by optimizing the internal bus architecture of the SoC, and improving the bandwidth of the DDR memory, the R-Car H3 realizes four times the memory bandwidth compared to the R-Car H2, which enables the system manufacturer to run multiple applications.
    Addressing the demand for higher resolution video playback on multiple displays, the R-Car H3 incorporates video codec engine exclusive to Renesas that supports new video compression formats and achieves two times the video playback performance of the R-Car H2.
    The R-Car H3 also incorporates enhanced security functions for a more robust boot protection process as well as protection against external cyber-attacks.
    The R-Car H3 delivers drastically improved functionality and system level performance, making it possible to utilize the R-Car H3 for a long period of time.
  • (3) Availability of SiP modules with external memory to reduce the design workload

    SiP modules support high-speed external DDR memory interface design with the R-Car H3. As the connection speed between the SoC and DDR memory rises, and the number of signal lines increases, burdens and complexities of PCB design increase. These have become important issues for system manufacturers. By developing modules with an SoC connected to DDR memory, Renesas is reducing the burden as well as the PCB costs and complexities associated with the design. In addition to the SoC and DDR memory, the modules include serial flash memory required for initial boot-up. This means the design tasks from boot-up through DDR memory operation can be eliminated and system manufacturers adopting the R-Car H3 can reduce their design tasks and risks.

The new R-Car H3 maintains a high level of software compatibility with the other SoCs in the R-Car Family already available: the R-Car H2, R-Car M2, and R-Car E2. The R-Car H3 will maintain high level software scalability for the third-generation R-Car Family.

“The R-Car H3 SoC has the all-round sensing, efficiency and safety characteristics that are essential in connected car technologies,” said James McNiven, general manager, CPU group, ARM. “Alongside the inclusion of the high performance ARM® Cortex®-R7 real-time processor, the SoC also capitalizes on the ARM Cortex-A57 and Cortex-A53 cores in an ARM big.LITTLE™ configuration. This has allowed Renesas to deliver advanced vision and detection capabilities while controlling power and achieving the stability that safety-critical electronics demand.”

“Imagination is delighted to see the introduction of the R-Car H3 which includes or our high performance PowerVR GX6650 graphics engine,” said Tony King-Smith, Imagination Technologies EVP marketing. “GX6650 delivers premium graphics performance and features to enable future cockpit experiences, as well as comprehensive GPGPU capabilities.”

“We are pleased to partner with Renesas to provide QNX® software support for the new R-Car H3 SoC,” said John Wall, Senior Vice President and Head of QNX Software Systems, a subsidiary of BlackBerry. “Through this collaboration, we can help accelerate the delivery of next-generation infotainment and ADAS systems that combine the performance of Renesas’ R-Car H3 SoCs with the proven reliability and scalability of QNX OS technology.”

“Next-generation automotive electronics must be designed with security and safety as the top priority,” said Tim Reed, Vice President of Advanced Products, Green Hills Software. “By offering our proven INTEGRITY real-time operating system and Multivisor secure virtualization solutions with the R-Car’s safe and reliable technologies, automotive OEMs and Tier 1’s can be confident in realizing this important design goal.”
