R-Car V3H System-On-Chip for automotive front cameras

Advanced Driving Assistance Systems (ADAS) and automated driving technologies such as autonomous-driving vehicles are now becoming more of a reality, thanks to the rapid enhancement in technologies. Renesas Electronics Corporation announced its new R-Car V3H system-on-chip (SoC) that delivers high computer vision performance and AI processing at industry-leading low power levels, targeting automotive front cameras for use in mass-produced Level 3 (conditional automation) and Level 4 (high automation) autonomous vehicles.

The new R-Car V3H system-on-chip (SoC) is optimised for use in stereo front cameras and achieves five times the computer vision performance of its predecessor, the R-Car V3M SoC targeting NCAP front cameras, announced back in April 2017. Part of the open, innovative, and trusted Renesas autonomy Platform for advanced driver assistance systems (ADAS) and automated driving (AD), the R-Car V3H enables design flexibility for Tier 1s and OEMs to map their own road from assisted- to highly- automated vehicles.

R-Car recognition technology
The R-Car V3H SoC focuses on architecture optimisation for computer vision processing, enabling all relevant ADAS functions from conditional to highly automated driving. Leveraging Renesas’ concept of heterogeneous computer vision cores based on the IMP-X5+ image recognition engine and dedicated hardware accelerators, the R-Car V3H achieves advanced sensing capabilities with algorithms including Dense Optical Flow, Dense Stereo Disparity, and Object Classification. The integrated IP for CNN accelerates deep learning at industry-leading low power levels of only 0.3W, achieving more than two times of the deep neural network performance of the R-Car V3M.

Scalability and cost saving
Relying on proven IPs already used in the R-Car V3M, the R-Car V3H includes a dual Image Signal Processor (ISP) that converts camera sensor signals for image creation and recognition processing. The re-use ensures scalability from NCAP systems -using R-Car V3M- to level 3 and 4 smart camera systems -using R-Car V3H-, reducing both development time as well as system costs by avoiding the need for ISPs in each camera. For further system cost savings, the R-Car V3H requires only a single LPDDR4 memory, reducing the cost for memory components compared to other solutions for front cameras.

Open platform solution
Tier1s and OEMs have the choice to develop a front camera solution by themselves or work with leading partners from the Renesas autonomy ecosystem, which is supported by leading front camera partners including HELLA Aglaia.

"The R-Car V3H specification and design was done by cooperating closely with front camera market leaders to ensure we addressed the requirements of those leading innovations on autonomous driving systems. As the automotive semiconductor industry leader, Renesas is committed to providing open, innovative, and trusted solutions for assisted and automated driving,” said Jean-Francois Chouteau, Vice President, Renesas Electronics Corporation. “Besides featuring state-of-the-art computer vision performance at a very competitive system cost, what our customers like above all with R-Car-V3H is being able to keep the freedom to implement a front camera with their own differentiators and still benefit from scalable solutions between R-Car V3M and R-Car V3H.”
