Renesas Technology's SH-MobileL3V Multimedia Processor Enables Mobile Phones
With Digital TV Broadcast Capabilities and VGA-Size Video
SAN JOSE, Calif.--July 11, 2006-- The Device Has an On-Chip High-Performance
Image Processing Engine for Video Recording and Playback, Plus a 5-Megapixel Camera-Module
Interface and More
Renesas Technology America, Inc., a subsidiary of the world's largest microcontroller
supplier, Renesas Technology Corp. today announced the latest expansion of its
popular SH-Mobile product line. The new SH-MobileL3V (product name: SH7354) is
a multimedia processor designed specifically to bring terrestrial digital broadcast
capabilities to mobile phones.
"This high-performance device is destined to further accelerate the race to pack
more and better TV and still-picture features into advanced mobile phones," said
Brian Davis, director, advanced solutions group, Renesas Technology America, Inc.
"The SH-MobileL3V multimedia processor is a key enabling component for new phone
models that can utilize digital broadcasting services. Those services are being
introduced in various countries throughout the world, boosting phone sales and
wireless usage."
The SH-MobileL3V multimedia processor incorporates a VPU4 (Video Processing Unit
4) video processing IP with powerful multimedia capabilities. For example, in
a phone for the Japanese market, the VPU4 IP can process terrestrial digital broadcasting
signals compressed using the H.264/MPEG-4 AVC moving-image compression standard
at a rate fast enough to encode and decode video at 30 frames per second at VGA
definition. That performance makes possible smooth video display and recording,
equivalent to that of a standard TV. The device also supports systems such as
DVB-H (Digital Video Broadcast for Handhelds) in Europe and DMB (Digital Multimedia
Broadcasting) in South Korea. Moreover, since the VPU4 IP can also handle MPEG-4
processing, the SH-MobileL3V can implement a variety of moving-image applications
such as video mail, videophones, and video clips.
Other multimedia-oriented features of the device include a direct connection
interface to a 5-megapixel-class camera module and a 24-bit LCD interface. The
camera interface allows high-speed capture of high-definition image data and versatile
image processing. It can perform electronic image zoom, screen overlapping, and
more; has a hardware cursor function; and supports YUV data of BT.709 specifications.
The latter makes it possible to extract TV broadcast data and convert it to a
JPEG image with no loss of image quality. The LCD interface supports a 16.78-million-color
LCD panel. That capability, together with the SH-MobileL3V's high-image-quality
compensation functions, enables the implementation of a variety of impressive
displays. The chip also includes a sound interface and communication interfaces,
as well as SD memory card and SIM card interfaces.
CPU core and VPU4 IP work together, so power consumption can decrease
At the heart of the SH-MobileL3V chip is a SuperH(R) type SH4AL-DSP CPU core
with cache memory, a direct memory access controller (DMAC) and a memory management
unit (MMU) that achieves high processing performance: 389 MIPS at its maximum
operating frequency of 216MHz. This CPU core provides unit-frequency processing
performance of 1.8 MIPS/MHz, sufficient for operating a browser with one-segment
broadcasting or a similar digital-TV capability. Moreover, the fact that the VPU4
IP performs almost all video processing by hardware frees up the CPU to execute
software-based computations and control activities. This division of tasks can
allow the design of mobile phones that use lower clock frequencies for decreased
power consumption and extended battery life.
The SH-MobileL3V multimedia processor is packaged in a compact 281-pin CSP (chip-scale
package: 9mm x 11mm x 1.4mm, with 0.5mm pin pitch). In a typical mobile phone,
the device connects to the baseband LSI device and performs voice, video, or similar
multimedia application processing. Dedicated interfaces allow easy connection
to the baseband LSIs of various types of phones. This feature, combined with accelerator
functions, system interfaces, and a power management function optimized for mobile
phones, allows customers to quickly produce advanced models offering market advantages.
