processor (IMP) dedicated for image processing. The
IMP takes the high-resolution images from the latest
automotive CMOS digital cameras and performs high-
speed, low-power signal processing. The RH850 MCU
accepts the chassis control commands from the R-Car
SoC and transmits these commands to the various
electronic control units (ECUs) used. This enables the
Nissan LEAF’s ProPILOT Park to achieve safe and
reliable parking operation.
“As part of our efforts to promote the spread of the driving
assistant technologies, Nissan has been the pioneer
in the industry in around view monitor implementation
thanks to Renesas” image processors,”said Takashi
Yoshizawa, Vice President and Alliance Global Director
of EE and Systems Engineering Division, at Nissan
Motor Corporation. “I am very pleased that together
with Renesas we were able to bring the ProPILOT Park,
which is a full-fledged automated-parking features in
our new Nissan LEAF.”ֲ
”Webelieve fromour expertiseand long-timeexperience
in the automotive area that, in addition to achieving
performance and quality, the balance between the
control of heat, space, and other parameters is also
essential,” said Ryuji Omura, Executive Vice President,
Renesas Electronics Corporation. “We are proud that
our track record has been recognized with the adoption
of our automotive chips in Nissan’s new automated-
parking system. Renesas is poised to delivering
innovative technologies for autonomous driving to
foster the advancement of the automotive industry.”ֲ
Based on the newly-launched Renesas autonomy, a
new advanced driving assistance systems (ADAS) and
automated driving platform, Renesas enables a safe,
secure, and convenient driving experience by providing
innovative solutions for next-generation car.
New High Resolution Audio SoC Supports
a Variety of Sound Sources
ROHM also offers the industry’s first high resolution
audio reference design
ROHM has recently announced the availability of a
high resolution audio SoC designed to act as the ‘brain’
in audio applications such as Bluetooth speakers, USB
DACs, and mini/micro component systems by carrying
out control and management of peripheral components
and input/output I/F as well as enable playback of a
wide range of audio sources.
In recent years, a variety of audio devices are required
to faithfully reproduce information from different sound
sources (media/music files) – not just high-resolution
audio.
However, in order to support a wide range of audio
sources multiple media decoders are required (i.e.
CD, USB, Bluetooth) along with additional peripheral
components, leading to challenges relating to increased
software complexity and development load.
For the audio sector ROHM not only offers general-
purpose ICs such as opamps, but audio-related ICs as
well, ranging from media decoders and speaker amps
to sound processors. This time, ROHM developed an
audio SoC that acts as the ‘brain’ of audio devices along
with a reference design that improves audio quality for
the entire system while minimizing development load.
The BM94803AEKU integrates a processor chip
with SDRAM featuring an optimized architecture that
leverages software and circuit elements such as ASIC
(Application Specific IC), MCU, and various media
decoders (developed by the ROHM Group) on a single
chip. The media decoder supports a wide range of
audio sources, and utilizing over 20 years of expertise
allows ROHM to ensure stable playback of damaged
CDs and even non-standard USB. In addition, SDRAM
is built in that contributes to greater miniaturization.
This SoC allowed ROHM to achieve the industry’s first
high-resolution reference audio design. The design
maximizes the performance of audio devices and
peripheral applications by configuring ROHM’s amp,
CD driver, and other elements around the audio SoC.
Furthermore, providing dedicated software enables
rapid development of audio devices capable of stable
playback of a wide range of audio sources, shortening
development time considerably.
