Tegra, developed by Nvidia, is a system on a chip (SoC) series for mobile devices such as smartphones, personal digital assistants, and mobile Internet devices. The Tegra integrates the ARM architecture processor central processing unit (CPU), graphics processing unit (GPU), northbridge, southbridge, and memory controller onto one package. The series emphasizes low power consumption and high performance for playing audio and video.

History

The Tegra APX 2500 was announced on February 12, 2008; the Tegra 6xx product line was revealed on June 2, 2008[1] and the APX 2600 was announced in February 2009. The APX chips were designed for smartphones, while the Tegra 600 and 650 chips were intended for smartbooks and mobile Internet devices (MID).[2]

The first product to use the Tegra was Microsoft's Zune HD media player in September 2009, followed by the Samsung M1.[3] Microsoft's KIN was the first cellular phone to use the Tegra,[4] however the phone did not have an app store, so the Tegra's power did not provide much advantage. In September 2008, Nvidia and Opera Software announced that they will produce a version of the Opera 9.5 browser optimised for the Tegra on Windows Mobile and Windows CE.[5][6] At Mobile World Congress 2009, Nvidia introduced its port of Google's Android to the Tegra.

On January 7, 2010, Nvidia officially announced and demonstrated its next generation Tegra system-on-a-chip, the Nvidia Tegra 250, at Consumer Electronics Show 2010.[7] Nvidia primarily supports Android on Tegra 2, but booting other ARM-supporting operating systems is possible on devices where the bootloader is accessible. Tegra 2 support for the Ubuntu GNU/Linux distribution was also announced on the Nvidia developer forum.[8]

On February 15, 2011, Nvidia announced the first quad-core SoC that will be used in many of the tablets to be released in the second half of 2011. The announcement was made at the February 2011 Mobile World Congress event in Barcelona. Though the chip has currently been codenamed Kal-El, it will likely be branded as Tegra 3. Early benchmark results show impressive gains over Tegra 2[9][10].

In January 2012, Nvidia announced that Audi had selected the Tegra 3 processor for its in-vehicle infotainment systems and digital instruments display.[11] The processor will be integrated into Audi's entire line of vehicles worldwide, beginning in 2013.

Tegra 3 (Kal-El) series

The Tegra 3 is functionally a SoC with a quad-core CPU, but includes a fifth "companion" core. While all cores are Cortex-A9s, the companion core is manufactured with a special low power silicon process that uses less power at low clock rate but does not scale well to high clock rates; hence it is limited to 500 MHz. There is also special logic to allow running state to be quickly and transparently transferred between the companion core and one of the normal cores. The goal is for a mobile phone or tablet to be able to power down all the normal cores and run on only the companion core, using comparatively little power, during standby mode or when otherwise underutilizing the CPU. According to Nvidia, this includes playing music or even video content.[18] Compared to Tegra 2, the ARM Cortex-A9s in Tegra 3 now supports ARMs SIMD extension, marketed as NEON. It can also output video up to 2560×1600 resolution and supports 1080p MPEG-4 AVC/h.264 40 Mbit/s High-Profile, VC1-AP, and DivX 5/6 video decode.[19]

The Tegra 3 was officially released on November 9, 2011.[20]
