Toshiba announces MPEG4 codec for mobile handsets
Toshiba announced a MPEG4 codec (coder/decoder) primarily designed for 3D graphics in mobile handsets.
According to the company, T4G chip (TC35285XBG) offers graphics acceleration, texturing, special effects and other visual capabilities that should considerably improve mobile graphics quality.
The majority of mobile devices today utilize software rendering that increase CPU load and its energy consumption. T4G has a special circuitry for 3D images processing. Besides, it has a JPEG codec for a 2-megapixel camera and QVGA display circuitry. The solution also features a 0.13µm 20Mbit DRAM chip.
Working at 125MHz the chip consumes 170-230mW (for graphics and video/audio, respectively). T4G voltages are 3.0V ± 10%, 2.5V ± 0.2V, 1.5V ± 0.1V. Samples will be introduced in Q2 2004, while the volume production should start in Q3 2004.
