Tegra

Nvidia Tegra is a system based on the ARM architecture, a single-chip system (SoC ) for mobile devices such as PDAs, mobile phones, cars, tablet PCs and multimedia player, the manufacturer Nvidia. Except for one or more ARM cores of the SoC also includes a graphics processor and integrated video decoder and encoder and fulfills all tasks of a chipset. He is among other things comparable to the Snapdragon from Qualcomm or OMAP from Texas Instruments.

Overview of the technology

APX 2500/2600

The first generation of Tegra based on a ARM11 MPCore. Manufacturing is the chip in 65 nm technology. Power consumption is according to the manufacturer's instructions at a maximum of 200 mW.

In the system, a graphics processor is integrated out of the ARM core, the processing power is comparable to the Nvidia GeForce 6 series. This allows high definition video up to 720 lines reflect both compress as well as in real-time and process photos up to 12 megapixels. As video codecs H.264, MPEG -4 and WMV9 are supported. The processor is ( so also Android ) supports both Microsoft Windows Mobile, as well as special Linux kernels.

Tegra 250

The Tegra 250 is an ARM Cortex- A9 MPCore with up to 1 GHz. The 3D performance was doubled compared to the previous models by the manufacturer. This is also used for netbooks like the Toshiba AC100. Initial tests show that the Tegra 250, depending on the operating system and test program used, can compete with Intel's Atom processors.

Use

The APX 2500 was officially launched on February 12, 2008 by Nvidia at the GSM World Congress in Barcelona. The processor is installed in mobile phones since 2009. The first media player with the chip was the Microsoft Zune HD, which has by the hardware platform high graphics performance. So the player 3D games and 720p video can play.

The Tegra 2 and 3 will be installed in various products such as smartphones, tablet PCs and single board computers since the end of 2010.

Embedded

Continue to exist for the embedded market processor modules from the following companies:

• Avionic Design Tamonten system consisting of: Evaluation board including FPGA, Tamonten NG Eval Carrier
• Tegra 2 or Tegra 3 processor modules with a focus on IO support

These modules are available for both individuals and companies individually or in combination with carrier boards and allow it to realize its own products or projects based on the Tegra processors. Thus, the Tegra 3 is, for example, in the new radio navigation systems in the new Audi A3 and VW Golf VII use.

Linux Support

Nvidia proprietary drivers for the Tegra as part of its Linux -for- Tegra development kit available. Nvidia and the Embedded Partner Avionic Design work on open- source drivers, which should be included in the Linux kernel.
