Tegra

From Wikipedia, the free encyclopedia
NVIDIA Tegra T20 (Tegra 2) and T30 (Tegra 3) chips.

Tegra is a system on a chip (SoC) series developed by Nvidia for mobile devices such as smartphones, personal digital assistants, and mobile Internet devices. The Tegra integrates an ARM architecture 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 would 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]

Nvidia announced the first quad-core SoC at the February 2011 Mobile World Congress event in Barcelona. Though the chip was codenamed Kal-El, it is now branded as Tegra 3. Early benchmark results show impressive gains over Tegra 2,[9][10] and the chip was used in many of the tablets released in the second half of 2011.

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.

In summer of 2012 Tesla Motors began shipping the Model S all electric, high performance sedan, which contains two NVIDIA Tegra 3D Visual Computing Modules (VCM). One VCM powers the 17-inch touchscreen infotainment system, and one drives the 12.3-inch all digital instrument cluster."[12]

Tegra 2

The second generation Tegra SoC has a dual-core ARM Cortex-A9 CPU (lacking ARM's advanced SIMD extension—NEON), an ultra low power (ULP) GeForce GPU with 4 pixel shaders + 4 vertex shaders,[14] a 32-bit single-channel memory controller with either LPDDR2-600 or DDR2-667 memory, a 32KB/32KB L1 cache per core and a shared 1MB L2 cache.[15] There is also a version of the SoC supporting 3D displays; this SoC uses a higher clocked CPU and GPU. Unfortunately the video decoder has been unchanged since the original Tegra which does not provide good HD playback and has poor format support. The video decoder is only capable of decoding Baseline profile HD format which is obsolete and which was never used to encode HD video for the web. Tests of even YouTube HD videos show that Tegra 2 based tablets cannot decode most YouTube HD videos smoothly without highly optimized software.

Tegra 3

The Tegra 3 (codenamed "Kal-El")[21] is functionally a SoC with a quad-core ARM Cortex-A9 MPCore 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.[22] Compared to Tegra 2, the ARM Cortex-A9s in Tegra 3 now supports ARM's SIMD extension, NEON. The GPU in Tegra 3 is an evolution of the Tegra 2 GPU, with three times the number of shader units (12 compared to 4) and higher clock frequency. 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.[23] The Tegra 3 was released on November 9, 2011.[24]

The Tegra 4 has full support for hardware decoding and encoding of WebM video (up to 1080p 60Mbit/s @ 60fps).[52]

Along with Tegra 4, Nvidia also introduced i500, a software modem based on Nvidia's acquisition of Icera, which can be reprogrammed to support new network standards. It supports category 3 (100Mbit/s) LTE but will later be updated to Category 4 (150Mbit/s).

Tegra 4i

The Tegra 4i (codenamed "Grey") was announced on 19 February 2013. With hardware support for the same audio and video formats,[52] but using Cortex-A9 cores instead of Cortex-A15, the Tegra 4i is a cut-down variant of the Tegra 4 and is expected to be included in future budget phones and tablets. Unlike its Tegra 4 counterpart, the Tegra 4i also integrates the Icera i500 LTE/HSPA+ baseband processor onto the same die. The Tegra 4i also features only 60 cores in its GPU compared to the 72 GPU cores found in the Tegra 4.

Upcoming releases

As with the Tegra 3, all upcoming Tegra SoCs have codenames that are references to comic book superheroes. Specifically, Superman (Kal-El), Batman (Wayne), Jean Grey (Grey), Wolverine (Logan), and Spider-Man (Parker).[59]

Nvidia's Project Denver is intended to produce a line of 64-bit chips that combine GPU and CPU functions in the same manner as the 32-bit Tegras, starting with Parker.[60]

Parker

The sixth-generation Tegra will feature Nvidia’s own custom general-purpose ARMv8-compatible core code-named Project Denver as well as code-named Maxwell graphics processing core with GPGPU support. The chips will be made using FinFET process technology, which likely means that it will be made using TSMC 16 nm or 10 nm FinFET manufacturing process. Nvidia Tegra “Parker” is due some time in the 2015–2016 timeframe.

  • Processor: Nvidia Project Denver ARMv8 (64-bit)
  • Improved GPU core with a shared architecture as in Maxwell with CUDA technology
  • FinFET transistors
  • About 100 times faster than Tegra 2
  • To be released in 2015

Linux support

Nvidia distributes proprietary device drivers for Tegra through OEMs and as part of its "Linux for Tegra" (formerly "L4T") development kit. As of April 2012, due to different "business needs" from that of their GeForce line of graphics cards, Nvidia and one of their Embedded Partners, Avionic Design GmbH from Germany, are also working on submitting open source drivers for Tegra upstream to the mainline Linux kernel.[61][62] Nvidia co-founder & CEO laid out the Tegra processor roadmap using Ubuntu Unity in GPU Technology Conference 2013.[63]
