One of the high points with the technology used in Sony's Playstation 3 console is the Cell processor technology. A similar concept could be coming to the PC, and you'll have Toshiba to thank, not Sony.
Toshiba's SpursEngine is based on the same Cell processor technology as found in the PS3 and is used to process HD video with its four Cell cores. The technology makes easy work out of encoding and decoding HD content and can upscale standard-definition video to high-definition video without bogging down the CPU. Toshiba is already using the technology in its Qosmio G50 and F40 notebooks and hopes to expand to the desktop market via add-in cards by the end of the years.
LeadTek and Thomson are already on board with plans to release a SpursEngine card within the next few weeks. LeadTek's version is expected to debut this month at about $286 and its Winfast PxVC 1100 card has already been shown at the Ceatec Exhibition in Japan. Thomson is targeting a November release in the $375 to $400 range
