Sun Microsystems acquired microprocessor
startup Montalvo Systems
for an undisclosed sum, the company confirmed Thursday.

"We believe acquiring these assets will enhance the current and future
products we are developing and expect them to contribute to future generations
of Sun's microprocessor technology which will in turn drive additional differentiation
for Sun's Systems products," said Dana Lengkeek, a Sun spokeswoman, in
an e-mail.

Sun is one of the few companies that continues to design microprocessors for
use in its own servers. For example, the company's UltraSparc
T2, formerly known as Niagara 2, is an octal-core chip that integrates other
components of a computer on the same chip. The processor is capable of running
Sun's own Solaris operating system and Linux.

Montalvo is believed to working on a low-power processor that aims to compete
with chips from Intel and Advanced Micro Devices. The unique feature of Montalvo's
design is the use of asynchronous processor cores. Instead of multiple, identical
cores found in Intel's chips, Montalvo reportedly plans to use different types
of cores, some more powerful than others, on the same chip to improve performance
and keep power consumption low.

Little information about Montalvo is available on the
company's Web site, which describes the company as just " a well funded
fabless semiconductor startup funded by prominent Silicon Valley venture capital
firms."

Among observers in the microprocessor industry, Montalvo was watched with a
level of interest similar to that of PA Semi, which was acquired
by Apple earlier this week in a deal reported to be worth US$278 million.
Unlike Montalvo, PA Semi has a chip in production, a dual-core processor based
on the Power architecture licensed from IBM.

Apple has not detailed its plans for PA Semi.
