High definition is all the rage on big-screen TVs.
But now, smaller devices will be empowered with this
crisp video content. Recent announcements should
give designers a lift for creating small devices with big
ideas for HD playback and recording.
HD FOR $99
At the recent Mobile World Congress
(MWC) in Barcelona, Nvidia
introduced a platform based on its
Tegra 600 series computer-on-a-chip.
Reportedly, the platform will enable
designers to build a $99, always-on,
always-connected HD mobile internet
device (MID) that can go days
between battery charges. This is the
price that carriers are expected to charge, since “always
on” implies 3G connectivity.
The hardware specs for a Tegra-based MID are
impressive (see the figure). These figures include 720p
and 1080p video playback; low power consumption,
described by the company as days of use between
charges; full Wi-Fi and 3G connectivity via an
STMicroeclectronics U335 modem; and optimized
hardware support for Web 2.0 applications for a true
desktop-class Internet experience.
But the platform doesn’t stop there. There’s a complete
software solution, too, including Microsoft
Windows Embedded CE, application viewers, a full
Internet browser, a user interface (UI) framework, a
board support package (BSP), a software development
kit (SDK), a Web mail client, and more.
The Tegra 650 includes on chip an ARM11
MPCore running at 800 MHz, an HD AVP (highdefinition
audio video processor) employing Nvidia
PureVideo technology, and an ultra-low-power
(ULP) GeForce GPU, among other components. For

OMAP 4 DEBUTS
Also announced at MWC, the OMAP 4 mobile
applications platform from Texas Instruments promises
stunning, multimedia-rich user experiences such
as 1080p video record and playback, 20-Mpixel imaging,
and approximately a week of audio play time.
TI says that the new platform provides significant
improvements in performance and play time compared
to today’s most popular smart phones, for example,
10 times faster Web page loading times, more
than seven times higher computing performance, six
times higher video resolution, 10 times better graphics
performance, and six times longer audio play time.
The OMAP 4 processor balances processing across
four main engines: a programmable multimedia
engine based on TI’s C64x DSP and power-efficient,
multiformat hardware accelerators; general-purpose
processing based on the dual-core ARM Cortex A9
MPCore supporting symmetric multiprocessing
(SMP) and capable of
speeds of more than 1 GHz per core;
a high-performance programmable
graphics engine; and an image signal
processor (ISP) for high-quality
video and imaging performance.
The OMAP 4 platform also
includes a comprehensive software
suite, power-management technology,
and other supporting components.

A TRIPLE PLAY
Last December, VIA Technologies announced a
three-chip platform that brings HD performance to
ultra-compact systems. Code-named VIA Trinity,
the platform meets the performance requirements for
displaying HD yet still operates within a comparably
low-power envelope.
VIA Trinity couples a power-efficient VIA processor
like the VIA Nano processor with one of VIA’s
highly integrated media system processors. It adds
the power of an onboard S3 Graphics PCI Express
discrete GPU to bring the latest in x86 technologies
to even smaller spaces.
VIA’s focus on power efficiency at the silicon level
has enabled the integration of all chipset core logic,
memory control, integrated graphics processor (IGP),
peripheral and networking connectivity, and multimedia
functionality into a single-chip solution, such
as the VIA VX800 media system processor.
Because of this, a discrete graphics accelerator can
be added to the mix without blowing the space or
power budget. And OEMs can offer systems with
superior computing, 3D graphics, and HD video performance.

MEMS MICROPHONES CORRECTION
In “MEMS Sound Off ” in our February 26 issue,
we incorrectly said “the International Trade Commission
(ITC) recently ruled that MEMSTech was
infringing on Knowles Acoustics’ packaging patents.”
Actually, the ITC has not yet made a final determination
as to whether MEMSTech has infringed on
Knowles Acoustics’ packaging patents.
