The Reality of Next-Gen Mobile Phones
Business Week, News Factor
December 5, 2006 - It is probably going to take years before the 3G standards battles get sorted out and the visions of high-powered, do-all, mobile phones becomes a reality for the majority of global consumers. "How are we ever going to deliver that in a world of diverging standards?" asks Guenter Weinberger, president and chief executive officer of Sandbridge Technologies. That is a question that has yet to be untangled.

ARCHITECTURES: Handset integration strategies vary
EE Times, Ron Wilson
07.25.2005 - In contrast, Sandbridge (White Plains, N.Y.) is responding to a potentially more serious problem with a radical change in architecture. The root of the problem appears to be the aborted rollout of 3G networks. Not only has 3G failed to become ubiquitous, but it is not even the primary network for most carriers in most areas. That has forced handset makers to support 2G and 3G air interfaces and basebands in parallel, soon to be augmented by the curtain call of other network interfaces about which handset makers are speculating.

If the company's chips have enough processing power, they could shift the device to the best available network for price, speed or power consumption, based on the user's priorities, he says. That capability might even come in handy in cars, Baron adds.

MEX: Flexible building blocks
PMN.co.uk, www.mobileuserexperience.com
07.28.2005 - For many years handset development has proceeded along two tracks: devices designed for GSM and devices designed for CDMA. One of the most basic design choices is the baseband processor where these functions are handled and, since these have always been done in hardware, there is relatively little flexibility. In some ways, you could say the user experience starts with this choice.

it appears, to radically change the economics of handset manufacturing
in two significant ways. First, a single model of phone could
be kept on the market for more than one generation of cellular

differ widely in the levels and kinds of service they offer.

Sandbridge Blasts Off at MPF
A Multithreaded Compound ISA for DSP Applications
By Max Baron - Very seldom, if ever, does one get an
opportunity to develop from scratch a new low-power architecture
and an advanced compiler. Most processor vendors can claim
to have created both hardware and breakthrough software, but
Sandbridge Technologies may be the one to have taken, at inception,
the extra step that brings technology closer to its peak. Many
recently introduced DSP architectures have concentrated on
delivering workload-optimized performance via massively parallel
processing at lower frequencies; some of these powerful cores
are intended to work in tandem with a generic DSP and a general-purpose
processor. Architects at Sandbridge, however, decided to adhere
to multiprocessor configurations and—in order to extract
performance—opted for operation at higher frequencies.
It is fortunate that, in their quest for performance, the architects
were forced to take a fresh look at compilers.

Sandbridge's SandBlaster DSP and Tensilica's FLIX
ExtremeTech
Intel's HyperThreading technology looks like child's play
compared to SandBridge's new 8-way multithreading capable DSP
(digital signal processor) targeted at 3G wireless devices.
Replicating and sharing a number of processor resources (that
takes about 15% more die area than a hypothetical single-threaded
version), up to 8 threads can execute simultaneously in this
chip. Apparently, the algorithms and processing steps required
for 3G communications can be efficiently allocated across multiple
threads and executed simultaneously. The Sandblaster is capable
of processing 10 billion multiply/accumulate operations per
second, and consumes less than 500 milliwatts on average. Special
logic ensures no single thread can dominate the instruction
cache, as each thread is only capable of evicting its own specific
subset of cache lines. Note that threads can read instruction
cache lines from other threads, so that cache is considered
to be shared among threads. For power savings, if a thread
is not used, it is turned off, and any functional units not
presently used can be temporarily powered down.

everything from GSM and WAP protocols, to multimedia-specific
algorithms like MPEG-4, to applications languages like Java.
By 2006, 140 million of the 700 million mobile phones will
have a digital camera attached, according to analyst firm In-Stat/MDR.
The reprogrammable nature of the core allows designers to
specify which wireless algorithm the core needs to process
at one time, the "software definition" of software-defined
radio.
