SANTA CLARA, Calif. -- August 28, 2014

Renesas Electronics Corporation (TSE:6723), today announced the availability
of its R-Car V2H, 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.

Renesas applied technology from its industry-leading R-Car SoCs for automotive
infotainment equipment and added high-performance image recognition and
low-power consumption technologies in the development of the R-Car V2H. 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. These types of
sophisticated systems demand substantially higher processing performance in
order to handle the expanded range of image recognition targets and increased
processing load imposed by multiple cameras with higher pixel counts. At the
same time, there is demand for both functional safety, to maintain high
quality and performance, and reduced power consumption. Finally, the rapidly
increasing cost of software development creates a need for better development
efficiency. The Renesas R-Car V2H addresses all of these requirements in a
single-chip solution.

“As a premier supplier of advanced semiconductor solutions to the automotive
industry, Renesas is mindful not only of the electronic system requirements of
today and tomorrow’s automobiles, but also the importance of safety,
especially with wider adoption of self-driving vehicles,” said Amrit
Vivekanand, vice president of automotive, Renesas Electronics America Inc.
“The R-Car V2H series delivers the imaging technologies, software tools, and
high-speed networking needed to develop robust ADAS systems that contribute to
smarter, safer automobiles.”

Key Features of the R-Car V2H SoC:

(1) Integration of essential ADAS functions on a single chip and low power

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. The overall architecture of the R-Car V2H is
optimized in order to reduce memory bandwidth usage and overall latency. Six
IMR channels can each support a high-resolution camera where the combined
output can produce high-definition surround view images. The IMP-X4, in
combination with the CPU, offers high performance for real-time processing of
image data as it is captured from the camera. The 3-D graphics core enables a
human-machine interface (HMI) that can deliver high visibility and easy
identification of hazards and is optimized to support texture mapping from the
camera feeds. While integrating the above functionality on a single chip, the
R-Car V2H device also incorporates functions to reduce power consumption to
the levels required by automotive systems. This includes a system design that
balances performance and power consumption, a power cutoff function for the
integrated cores, and a DDR3-SDRAM power backup function.

(2) Expansion of image recognition library support to include an open source
library (OpenCV^1) for improved software development efficiency

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.

The Renesas exclusive image recognition library support has been expanded to
include an open source library (OpenCV), substantially increasing the
efficiency of software development for the customer. The image recognition
library does not require fine tuning to extract full performance from the
image recognition core, delivering consistently stable performance and
allowing for smooth software upgrades. In addition, the library is backward
compatible with the IMP series employed in the earlier R-Car H1 and SH7766
Renesas products, making it easy to reuse existing software resources.

(3) Ethernet AVB in combination with optimized video codecs for
next-generation automotive networks and camera systems

Ethernet AVB offers features such as guaranteed bandwidth and synchronization
of multiple cameras. Moving forward, it is expected to become the mainstream
technology for automotive high-speed networking. The R-CAR V2H includes a
gigabit Ethernet AVB controller to work with next-generation automotive

In combination of the introduction of the Ethernet AVB technology with
optimized features for multiple-camera reception, Renesas also integrated
multiple-channel video codecs supporting up to 5 high-resolution cameras in
parallel. In order to support technical transition processing of video codecs
for surround-view monitoring systems, the R-Car V2H supports MJPEG & H.264.

Based on long experience in functional safety for embedded systems, the R-Car
V2H has been designed to achieve high level functional safety. For example,
ECC has been implemented on external memory and CPU caches in order to support
system manufacturers’ safety concepts. Additionally, the hardware CRC
functionality makes it easy to achieve end-to-end protection of data
transfers. In addition, the early adoption of the highly reliable INTEGRITY®
real-time OS from Green Hills Software is an important step toward achieving
functional safety in both hardware and software.

“Our partnership with Renesas has allowed us to develop an innovative solution
for the new revolutionary R-Car V2H ADAS platform,” said Tim Reed,
vice-president of advanced products at Green Hills Software. “By introducing
the industry’s most trusted real-time operating system-INTEGRITY-and its award
winning security and functional safety architecture, Renesas has created an
offering that delivers guaranteed real-time determinism and safety to its
customers. When I go out and buy a new automobile in the future, I will drive
easier knowing that this platform is riding alongside me, guiding my car, and
helping me and other drivers stay safe.”


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.
