ARM Details Cortex-A9
At the ARM
Developers Conference today, ARM unveiled its next-generation "Falcon" CPU,
officially called Cortex-A9. Although the A9 is technically ARM's
top of the line, it's more likely to be used in lower-cost designs
than its predecessor, Cortex-A8. That's because the A8 was ARM's
first "hard" core: optimized to achieve up to 1GHz, but
only in a specific IC process. Like other ARM cores, the A9 is
synthesizable, so it can be used in any IC process. The synthesizable
design can easily be configured to change the cache sizes or add
a floating-point unit or NEON multimedia accelerator.
According to ARM, the A9 targets 500MHz in a typical 65nm LP process,
about the same clock speed as the synthesizable version of the
A8. The new design, however, has several features to improve performance
per cycle. It uses a shorter, flexible pipeline to reduce pipeline
delays and misprediction penalties. The A9 can reorder instructions
to avoid stalls, whereas the A8 is a strictly in-order machine.
ARM says that these new features do not appreciably increase die
area or power consumption, although it did not disclose comparative
data for its new CPU.
For high-end applications, the A9 supports configurations with
up to four cache-coherent CPUs connected through a single high-speed
to a unified level-two (L2) cache. ARM quotes this configuration
at a clock speed of 1GHz in a 65nm GP process. The CPU complex
connects to the rest of the SoC through one or two 64-bit AMBA
buses. The multicore configuration could be used in set-top boxes,
media gateways, and other wired consumer devices.
Cortex-A9
is now available for design starts, and ARM expects the first
A9-based products to sample in mid-2008. That would be just
18 months after the first A8-based processor, the OMAP3 from Texas
Instruments. At 550MHz, the OMAP3 falls well short of the 1GHz
claimed for the A8, and the actual speed delivered by the A9 remains
to be seen. But the new design is a clear step forward for ARM,
and the A9's multiprocessor capabilities should open new high-end
markets. —Linley

Broadcom
Delivers HD VideoCore
Earlier this week, Broadcom announced that sampling of
a new mobile multimedia processor, the BCM2727, using
its third-generation
VideoCore technology. Enhancements over the prior generation
include a 3D accelerator supporting OpenGL ES 2.0 and rendering
32 million triangles per second, an image-processing pipeline
capable of sustained processing of 15 frames per second
of 12 megapixel images, and 720p HD video encoding
(H.264) and
HDTV playback. A combination of two vector processors derived
from earlier VideoCore processors and hard-wired engines
handle these functions.
Power dissipation for the 3D engine is about 130mW; for
the HDTV encoder it is about 450mW including the stacked
SDRAM
in the BCM2727. Broadcom expects to qualify the chip
for production in 1Q08, and for it to be used in
media players
and handsets. Owing to the long design cycle for handsets,
the first of these are expected to appear in 2010. Media
players could appear as early as the end of 2008.
Handsets, even in 2010, seem unlikely to take advantage
of the full capabilities of the BCM2727. Even if attached
to
an HDTV monitor, they lack the gigabytes of storage
needed for HD video programs. Few handsets have the
lens system,
much less the imager, to take 12MP photos or HD video.
The new chip is better suited to next-generation media
players
and hybrid devices with high-end video features. The
chip also demonstrates that Broadcom has the capability
to supply
the multimedia needs of handsets now and well into
the future. —Joe

MediaTek Acquires ADI's Basebands
Last month, Analog Devices (ADI) announced plans to sell its
money-losing cellular baseband business to Taiwan's MediaTek
for about $350
million in cash. MediaTek will acquire ADI's SoftFone baseband
processors and RF transceivers. ADI will continue to offer its
mobile-TV products (from its Integrant acquisition) as well as
analog components for mobile phones. Despite overall market growth,
SoftFone revenue declined in 2005 and 2006, reaching $239 million.
This decline left ADI with only 2.9% of the baseband market,
according to The Linley Group data.
MediaTek, in contrast, surged to 5.3% of the overall baseband
market in 2006, due mainly to sales of GSM processors into
China and other
low-cost markets. The company is unlikely to be interested
in ADI's GSM products, which have been losing share to
MediaTek's
existing
chips. But ADI is one of only two companies with a proven,
integrated baseband chip for TD-SCDMA, China's 3G cellular
standard. This
technology will help MediaTek expand its market share in China.
ADI also has a UMTS (3G) processor, which MediaTek can use
to move its product line upscale, enabling it to compete
in Europe
and
other 3G regions. In the deal, MediaTek acquires significant
design wins at LG, the fifth-largest handset vendor, including
some versions
of LG's hot "Chocolate" phone.
MediaTek is a rapidly growing and highly profitable company
that can invest some of those profits in expanding its
handset business.
No longer just a GSM vendor, the company now has the technology
to compete in the 3G market, both in China and around the
world. Including the SoftFone revenue, MediaTek is likely
to surpass
both Infineon/Agere and Freescale in 2007 to become the
third-largest vendor of cellular baseband processors. —Linley

Report
Highlights: Guide to Mobile TV Chips
The Linley Group is pleased to announce imminent availability
of A Guide to Mobile
TV Chips. Mobile TV is a complex market, with
multiple standards addressing the needs of various regions. Japan
uses a mode of ISDB-T, 1Seg, for its mobile standard. Qualcomm
has succeeded in getting its MediaFlo standard accepted in the
U.S. and is pushing for its use in other countries. Several deployments
using the T-DMB standard, derived from DAB radio, have taken place
around the world.
The technology's notable success has been in South Korea, where
it rapidly overtook the S-DMB standard. China will deploy a native
technology, most likely CMMB, for its national standard. Italy
is the site of the first commercial DVB-H networks, and the DVB-H
standard is likely to be used across Europe and in several Asian
countries.
The proliferation of standards has enabled a large number of
mobile-TV chip suppliers. DiBcom is the dominant DVB-H supplier,
and its
parts are the de facto benchmark for receiver performance.
Challenging DiBcom are startup Siano Mobile Systems, which
touts the low
power and multi-standard support of its design, and Newport
Media, one
of the first companies to offer high-performance, single-chip
receivers. Newport is also the first company to offer a single-chip
1Seg receiver
and is likely to be the first company besides Qualcomm to offer
a MediaFlo part. In 2008, Broadcom and Infineon expect to ship
single-chip DVB-H receivers, challenging DiBcom's leadership.
Single-chip integration is also shaking up the T-DMB market.
Both Analog Devices and GCT Semiconductor offer integrated
T-DMB receivers.
LG Electronics has built MPEG decoders into its T-DMB demodulator
to reduce system cost.
Each
standard and regional market can support multiple suppliers,
but we expect the vast herd of suppliers will be thinned. A
Guide to Mobile TV Chips provides a detailed
comparison of dozens of mobile-TV ICs, helping OEMs, investors,
and
competitors
identify the most likely winners and losers. It also provides
detailed forecasts for mobile-TV chips by region, standard,
and application.
