Renesas new R-Car device offers high-res image recognition for driver assistance systems

The R-Car V2H from Renesas Electronics Corporation is the company's newest system-on-a-chip (SoC) implementing state-of-the-art image recognition technology to support high-resolution surround viewing in advanced driver assistance systems (ADAS). This is the first R-Car ADAS device from Renesas and includes additional functionality for higher performance, lower power, and improved safety in traditional and emerging self-driving vehicles.

The R-Car V2H enables embedded system manufacturers to deliver high-resolution surround-view monitoring systems, with multiple cameras for advanced point-of-view switching. This includes rear-view and surround-view capabilities that expand what is seen by the system to every direction around the vehicle, aiding in driver oversight prevention.

The R-Car V2H SoC incorporates the IMR, a core dedicated to viewpoint conversion, the Renesas IMP-X4 image recognition core, and a 3-D graphics core, all of which provide the imaging-related technologies needed to support ADAS requirements on vehicles targeting new government regulations and insurance safety ratings. Six IMR channels can each support a high-resolution camera where the combined output can produce high-definition surround view images.

The IMP-X4 image recognition core delivers image recognition processing performance that is approximately eight times that of the earlier Renesas SH7766 and approximately four times that of the R-Car H1. The IMP-X4 incorporates six programmable image processing accelerators making possible image recognition functionality involving, for example, processing of input from multiple cameras, while altering their configuration as needed.

Ethernet AVB offers features such as guaranteed bandwidth and synchronization of multiple cameras. The R-CAR V2H includes a gigabit Ethernet AVB controller to work with next-generation automotive networks.

Samples of the R-Car V2H SoC will be available in September 2014. Mass production is scheduled to begin in October 2016, and is expected to reach a combined production volume of 500,000 units per month by October 2017.
