Seven Steps to Software Security

Nvidia has rolled out its latest mobile phone graphics chip, an upgraded version of the currently available GoForce 3D 4500.

The new chip, the 4800, adds 30fps MPEG 4 decode and encode at image resolutions of up to 640 x 480 to the 4500's spec. sheet. It can also compress three megapixel images using JPEG, optimising each image's compression level to maximise available memory.

The 130nm 4800 offers 640 x 480 LCD support and can handle real-time, full duplex, two-way video conferencing at 352 x 288 and 30fps, Nvidia claimed.

Like the 4500 before it, the 4800 sports Nvidia's nPower power-conservation technology, which shuts down pipeline stages and other SoC components when they are not needed.

The chips provide pixel-shader programmability with 40-bit colour support, and bilinear and trilinear filtering, though there's no anti-aliasing, a key selling point of a number of rival designs, such as Falanx's Mali cores.

The GoForce 3D chips host a 128-bit memory interface and integrate 1.3MB of 128-bit SRAM. They are OpenGL ES and MD3D compliant.

Nvidia didn't say whether the 4800 is shipping or not, but it did say it expects handsets containing the chip to ship by the end of the year. ®
