MPEG-4 Codec Delivers Optimal Video with the World's Lowest Power Consumption
of Just 13mW

SUNNYVALE, Calif., March 30 /PRNewswire/ -- Building on its experience and
expertise in graphics display control technology, Fujitsu Microelectronics
America, Inc. (FMA) today introduced two new advanced Mobile Media Processors
(MMPs) for mobile phones and other handheld devices, which will be available
in sample quantities in April 2004.
The new MMPs (MB86V00 and MB86V01) incorporate MPEG-4 and JPEG hardware
encoding and decoding functionality. They include two-dimensional and
three-dimensional (2D/3D) graphics accelerators with a 24bpp display
controller. Two camera modules (up to two Mega-pixels) can be attached to the
MMPs simultaneously via a YUV interface, and can be activated at alternating
intervals. The MB86V00 and MB86V01 can interface with two LCDs, enabling users
to display multiple images simultaneously on two separate screens as is
required for flip phone designs. The devices feature a flexible CPU interface
that enables easy connection to existing baseband or application processors.
Other features include the ability to display three windows, and to mix
multiple visual images using alpha blending (transparency). The devices also
provide hardware support for image scaling and rotation, and also include
BitBlt and texture-mapping features.
When the internal clock operates at 13.5MHz, and the MPEG-4 codec
(QCIF@15fps) is functioning, the device consumes just 13mW (codec core), a
much lower power consumption than any other such device. It is also possible
to operate the MPEG-4 codec (QVGA@15fps) with the internal clock at 54MHz,
allowing not only low power consumption but also high performance.
To eliminate the need for external memory, the MB86V00 device incorporates
64Mbits of SDRAM as a system-in-package. To minimize power requirements,
sophisticated clock-gating techniques shut down logical functions when they
are not needed or not in use. The advanced power management hardware is
managed by Fujitsu's firmware that monitors various chip activities and
throttles the clocks accordingly.
"Adding one of these MMPs to the central processor typically found in
handheld devices enables the device to handle sophisticated graphics with
ultra-low power consumption," said Keith Horn, vice president of marketing for
Fujitsu Microelectronics America. "With the proliferation of features in
mobile phones and PDAs, there is a growing need for a specialized application
processor to handle multimedia functions without sacrificing battery life. Our
new devices meet those requirements."
MMP Expertise Based on Fujitsu's Leadership in Graphics Display Controllers
The design expertise for the new MMP series comes from Fujitsu's technical
leadership in graphics display controller devices, which were developed in
collaboration with major automobile manufacturers and are now installed in
more than 60 percent of the dashboard navigation systems sold worldwide.
Fujitsu's graphics display controllers provide multiple layers, special
line-drawing functions, numerous windows with resizing and transparency for
overlapping and video input.
"The Mobile Media Processor combines Fujitsu's proven graphics processing
with MPEG-4 and JPEG hardware compression in a single chip, enabling
high-quality images to be delivered to small-form-factor displays," said
George Wu, FMA's director of Technology Solutions/ASSP product marketing. "Our
MMPs now meet the complex and intensive processing required for video and
graphics in mobile products, with a minimum of power."

Rapid, Reliable Operation
When mounted in a 3G mobile phone, the MMP captures images through one of
the two camera ports and then compresses the images using JPEG for still
shots, or MPEG-4 for moving pictures. The processor will also render 2D
graphics for maps, or 3D graphics for games and other forms of animation. The
MMP incorporates two LCD interfaces, so images can be displayed on either one
or two LCD screens.
To ensure that all these functions perform optimally and do not interfere
with each other, Fujitsu provides OS-independent driver software equipped with
host processor support code. The software performs power-management operations
by monitoring I/O and macro block activity, and determines when to throttle
the various clock domains up or down. The optimized driver tools significantly
reduce development time and increase device efficiency.

Pricing and Availability
The MMPs support a pair of camera devices. Built using Fujitsu's
low-leakage 0.18-micron CMOS process, they are housed in 289-pin FBGA
packages. The MB86V00 device incorporates 64Mbits of SDRAM as a
system-in-package, and mass production of both MB86V00 and MB86V01 will start
in September. Samples are available at $45 each starting in April.

MB86V00/MB86V01: Main Features

Low Power Consumption
Because they implement almost all image-processing functions through
dedicated circuits, the MMPs require much less power than a general-purpose
CPU implementing those functions through software.

MPEG-4 Compression and Decompression
The MMPs can compress and decompress MPEG-4 content at QVGA resolution
(320 x 240 pixels), 15 fps, and can also output ITU-RBT.656 video.

JPEG Compression
The MMPs can compress still images up to 2MPixels.

2D/3D Rendering
The MMPs can generate up to 27MPixels per second for sophisticated graphic
displays.

Two Camera Inputs and LCD Circuits
The MMPs can handle up to two camera inputs of 2MPixel resolution and two
LCD displays of maximum VGA resolution (640 x 480 pixels).

Included Software: Main Features

Flexible control over screen layout, complex display options
Each display can independently carry video, still photos, text, graphics
and data, with specified positioning and layering.

Support for complex image-processing systems
The MMPs can be controlled in high-level process units such as "video
capture," making it easier to develop image-processing systems.

Embedded power-management features
Software manages the chip's operation, throttling the clock signal to
inactivate parts of the processor to limit power consumption.
