| Toshiba's New MPEG-4 Encoder and Decoder LSI Integrates
High Performance 3D Graphics Engine
23 February, 2004
TOKYO -- Toshiba Corporation today announced the launch of a powerful MPEG-4 encoder and decoder LSI that brings video-game-grade 3D graphics to cellular phones. The latest addition to Toshiba's T series of MPEG-4 LSI, the T4G (part number: TC35285XBG) supports fast rendering of graphics, including advanced shading, texture mapping, special effects and other visualization functions, enabling mobile phones to offer high-resolution 3D graphics matching those of current game consoles.
Most of today's advanced mobile phones render 3D graphics by software,
an approach that severely burdens the CPU and increases power consumption.
The T4G instead integrates a dedicated circuit for high-grade 3D graphics.
At a time when cellular phones are diversifying to become games platforms
and personal GPS systems, the T4G delivers a timely solution that supports
improved graphics and renders video sources with a drawing performance
of 125-million pixels a second.
Sample shipments of T4G will start in the second quarter of calendar year 2004, at a unit price of 4,000 yen. Mass production is scheduled to start in the third quarter of 2004.
Broadband data communication and larger, high quality LCD are fueling demand for high performance mobile phones, said Yasuhiko Fujita, Senior Manager of the System LSI Division at Toshiba Corporation's Semiconductor Company. With our T series of MPEG-4 codec LSIs, we have led the way in bringing video to mobile phones, since as long ago as 1998. The T4, the predecessor of the T4G, is already in use in the latest phones on the Japanese market. The launch of T4G, with its 3D graphics processor and other image processing circuits, goes even further to meeting the phone makers' requirement for high level performance in compact design.
