IBM unveils power-paring chip

IBM Corp. unveiled an ultra-low power chip Friday that it said will reduce power consumption in battery-operated portable consumer electronic devices and improve power efficiency, both in active and standby modes.

The new IBM Power PC 405LP chip is the first in what will be a family of products developed in the company's Low-Power Computing Research Center at IBM's Austin Research Laboratory in Texas.

By using hardware accelerators, the chip off-loads processor demands, enabling it to shut off parts of the device that are not in use. The 405LP also reduces active power by scaling back the processor performance to the levels required to support the application. Additionally, the chip also has a mode in which power is reduced to almost zero, but still provides an "instant-on" response to external stimulus, such as a stylus pen.

IBM estimates that the 405LP's power conserving features and innovative build, utilizing new materials such as copper wire and silicon-on-insulator technology, will allow products to consume 10 times less power than they do today. The company's rally around low-power products comes amid increasing calls for expanded functionality and efficiency in third-generation devices.

IBM is currently working with a number of consumer electronics companies, such as PDA (personal digital assistant) and next-generation cell phone providers, to incorporate the new chip, a company spokesman said Friday.

The 405LP will be incorporated in sample designs by the first quarter of next year and will be available globally in the consumer market later next year, he said.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
