Sun Microsystems Plans to Unveil
A Fast New Chip, Challenging Intel
By DAVID P. HAMILTON

Sun Microsystems Inc., which is already working to overturn the
established order in the software world with its Java technology, is now
readying a similar attack on the chip industry.
Monday, Sun, based in Palo Alto, Calif., will disclose its plans for a
microprocessor with a radical new architecture designed to handle
complex graphics, voice and video, challenging Intel Corp. and other chip
makers in the fast-growing market for communications and
media-processing chips. A brainchild of the company's chief scientist, Bill
Joy, the new chip is dubbed MAJC, which is pronounced "magic" and
stands for "microprocessor architecture for Java computing."
Thanks to an unusual design that essentially
turns a single chip into a parallel-processing
system, MAJC chips should be able to display
complex graphics and handle digital-communications tasks at extremely
high speeds -- far faster than a general-purpose Intel chip, for instance.
Sun officials already audaciously refer to MAJC as "the most important
semiconductor architecture of the next 20 years." In part, that's because
the chip is particularly well-suited, they say, to handling the enormous
streams of visual and audio data expected in the multimedia age. In
addition, MAJC should yield a family of microprocessors that are easy to
program using Sun's Java language, that can be used in everything from
cheap consumer devices to Internet server computers, and that over time
will grow even more powerful, and more quickly, than rival chips.
With MAJC, "it will be much, much easier to build media capabilities into
commonplace devices and networks," Mr. Joy says.
Sun, for instance, claims that within several years, it should be possible to
generate an interactive computer-animated movie like "Toy Story" in real
time using a single MAJC chip -- a task that took roomfuls of graphics
servers several weeks. Analysts are reserving judgment on such claims
until Sun formally discloses the details of the architecture on Aug. 16. But
those familiar with the broad outline of Sun's new chip are impressed with
MAJC's innovative design.
MAJC's central advantage derives from Sun's decision to design its chips
with modular, high-performance computing engines, each of which is really
a processor in its own right. Where a typical PC microprocessor consists
of as many as three separate computing engines, each focused on handing
a different type of data, a MAJC chip will be built out of a number of
identical general-purpose processors that can split up computing tasks in a
more efficient manner. That design turned out to be ideal for handling
multimedia data, which can easily be split up into independent tasks and
farmed out to processors on a single MAJC chip, says Marc Tremblay,
MAJC's chief architect. "If you are processing video data, you could have
one processor working on the upper half of the image, and the other on the
lower part," he says.
Other advantages also flow from MAJC's basic design. Because it is
conceptually as simple to design a MAJC chip containing, say, eight
processors as one with a single processor, Sun figures it can sell cheap
versions of the chip for use in inexpensive consumer-electronics devices as
well as high-end versions to handle enormous streams of data coursing
over the Internet or through corporate networks.
Such parallel processing at the chip level, while not entirely a new idea,
hasn't fared well in practical applications because it's generally difficult to
write software that takes advantage of the design. Java, however, is a
relatively simple computer language that's already designed to support
parallel processing. Sun, however, isn't being a zealot about Java; MAJC
chips will also run programs written in other languages, such as C and
C++.
Totally new microprocessor designs aren't launched very often, and Sun's
decision to jump into this field shows how crucial it thinks the multimedia
age will be.
It's still a risky bet, though; several start-ups that tried roughly the same
thing have crashed and burned over the past several years, after their chips
failed to win broad acceptance. Intel, which has also moved aggressively
into communications-related chips, will also pose a competitive threat. |
