Kit accelerates development of autonomous vehicles

Based on Renesas Electronics’ ISO 26262 ASIL-B SoC and ISO 26262 ASIL-D MCU, a highly automated driving (HAD) kit delivers computing performance targeted at automotive functional safety to reduce development time of electronic control units (ECUs).

It is based on two R-Car H3 Starter Kit Premier and the automotive control RH850/P1H-C microcontroller (MCU), making it compliant with both the ISO 26262 ASIL-B functionality safety standard and the ISO 26262 ASIL-D standard. System developers can immediately evaluate functions and software in an environment that is similar to the development of ECUs, to reduce time and effort when porting software to the actual ECUs.

 The HAD kit supports software development and software verification that Tier-Ones and OEMs use for automotive ECUs. This is integrated in a robust housing with multiple interfaces to provide rich connectivity close to actual automotive ECUs, claims the company.

 The kit simultaneously provides the computing power required for autonomous driving, maintains a high level of safety, and ensures quality as it connects two R-Car H3 SoC-based starter kits and one RH850 P1H-C MCU through on-board high-speed interfaces. It provides connection to peripherals using multiple external interfaces, such as CAN-FD, FlexRay and Ethernet.

 The housing allows testing in the lab as well as in test drives that meet automotive requirements, which are demanding in terms of operating temperature, low power consumption and small implementation size.

 As well as compliance to ISO 26262 ASIL-B and ISO 26262 ASIL-D, the  ARM Cortex-A57/A53-based SoCs achieves processing performance of over 40,000 DMIPS.

The R-Car H3 is also ISO 26262 ASIL-B compliant and has powerful graphics processing units (GP-GPU) core by Imagination Technologies’ PowerVR GX6650 and Renesas’ IMP-X5 parallel programming core. The latter is claimed to have optimal structure for processing computer vision and deep learning, to enable the advanced calculation processing required for autonomous driving.

 The RH850/P1H-C is a high-end safety MCU with a built-in hardware security module that conforms to the ISO 26262 ASIL-D safety standard. It features a large capacity memory, a high-performance CPU that achieves processing performance of 1,344 DMIPS and rich communication functions for communication networks on one single chip.

Support for multiple interfaces includes five 100Mbit Ethernet Broad R-Reach ports, 1Gbit Ethernet, controller area network (CAN) with CAN-FD and FlexRay.

 In addition, up to 16 camera inputs are available to allow direct connection and image processing by the R-Car H3.

 The datalogging function is complemented by a solid state drive support as well as a USB 3.0 connection to enable the recording of test drive data. It also provides high-definition multimedia interface (HDMI) output for the visualisation.

 The new kit is complemented by Renesas’ Linux Yocto-based board support package for the R-Car H3 as well as software required for the RH850/P1H-C. Additional software will be available from partners.

Samples of the HAD solution kit are scheduled to be available in February 2017.
