Nvidia Jetson is a series of embedded computing boards from Nvidia. The Jetson TK1, TX1 and TX2 models all carry a Tegra processor (or SoC) from Nvidia that integrates an ARM architecture central processing unit (CPU). Jetson is a low-power system and is designed for accelerating machine learning applications.
The Jetson family includes the following boards:
- In late April 2014, Nvidia shipped the Nvidia Jetson TK1 development board containing a Tegra K1 SoC in the T124 variant and running Ubuntu Linux.
- The Nvidia Jetson TX1 development board bears a Tegra X1 of model T210.
- The Nvidia Jetson TX2 board bears a Tegra X2 of microarchitecture GP10B (SoC type T186 or very similar). This board and the associated development platform was announced in March 2017 as a compact card design for low power scenarios, e.g. for the use in smaller camera drones. A matrix describing a set of performance modes was provided by the media along with that. Further a TX2i variant, said to be rugged and suitable for industrial use cases, is mentioned.
- The Nvidia Jetson Xavier got announced as a development kit in end of August 2018 with a fulfillment promise of "early September". With the announce came a product image and some technical specifications. Indications were given that a 20x acceleration for certain application cases compared to predecessor devices should be expected, and that the application power efficiency is 10x improved.
- The Nvidia Jetson Nano was announced as a development system in mid-March 2019, with the a Development Kit available for pre-order at announcement and promise of wide availability in "June 2019". The focus of the discussion around this product was for hobbyist robotics due to the low price point. The final specs expose the board being sort of a power optimized, stripped-down version of what a full Tegra X1 system would mean. Comparing in more detail only half of the CPU (only 4x A57 @ 1.43 GHz) and GPU (128 cores of Maxwell generation @ 921 MHz) cores are present and only half of the maximum possible RAM is attached (4 GB LPDDR4 @ 64 bit + 1.6 GHz = 25.6 GB/s) whilst the available or usable interfacing is determined by the baseboard design and is further subject of implementation decisions and specifics in an end user specific design for an application case.
The published performance modes of the Nvidia Jetson TX2 are:
|Mode||Max Clocks (Denver2 + A57)||Max-P (Denver2 + A57)||Max-P (only Denver2)||Max-P (only A57)||Max-Q (only A57)|
|GPU Clock / MHz||1302||1122||854|
|Denver2 Clock / MHz||2000||1400||2000||stopped||stopped|
|Cortex-A57 / MHz||2000+||1400||stopped||2000||1200|
|TDP / W||might vary||15||15||15||7.5|
The published operation modes of the Nvidia Jetson Nano are:
|GPU Clock / MHz||921||640|
|Cortex-A57 / MHz||4x 1428||2x 918|
|TDP / W||10||5|
Various operating systems and software might be able to run on the Jetson board series.
JetPack is a Software Development Kit (SDK) from Nvidia for their Jetson board series. The official Nvidia download page bears an entry for JetPack 3.2 (uploaded there on 2018-03-08) that states:
Even if QNX is not widely announced for the Jetson platform still there are success reports of installing and running specific QNX packages on certain Nvidia Jetson board variants. Namely the package qnx-V3Q-23.16.01 that is seemingly in parts based on Nvidia's Vibrante Linux distribution is reported to run on the Jetson TK1 Pro board.
