Leadtek to show external SpursEngine processing device

The prototype device will boost the graphics processing power of laptop computers

A prototype device due to be shown in Tokyo Wednesday may give laptop computers a better shot at performing heavy-duty video processing.

Space and heat considerations often limit the amount of computing power that can be packed into laptops.

But Taiwan's Leadtek plans to unveil a prototype external video processor that brings the power of Toshiba's SpursEngine chip to portable platforms.

The SpursEngine was developed by Toshiba and is based on the same architecture as the Cell Broadband Engine microprocessor that powers the PlayStation 3 console.

While the Cell contains a Power PC core and eight "Synergistic Processing Elements" cores, the SpursEngine contains only four of the SPE cores.

The chip also contains a hardware encoder and decoder for MPEG2 and MPEG4 AVC/H.264 video and is designed to be used as a PC co-processor handling of calculation-intensive work such a real-time high-definition graphics processing.

Leadtek already offers a plug-in SpursEngine board for desktop PCs and the prototype device essentially packages the board in a case with PCI Express connector for use with laptops.

The device will be on show at the Embedded Systems Expo that runs from Wednesday to Friday.

Leadtek hasn't detailed when it will be available or a likely price but the PC Card costs about ¥29,800 (US$308).

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.
