****ARM 阵营要拿什么出来跟 Wintel 拼?早上的本场 MTK记者会就给了作者们答案。大概来讲,Snapdragon 的表征正是轻、薄、凉、省 —
绝大部份现场展览的参照机型拿起来都轻若无物,何况都尚未散热口!那么些机器都尚未打出标准来(真的上市的话应该也会略有分化),但只是就
Form factor 来讲,ARM netbook
确实是令人梦想啊!机器的肖像在承袭读书里。—-<Computex 二零零六: A Taste
of Snapdragon Netbook to Come>So what does the ARM camp have in store
to compete with Wintel? We got the answer from this afternoon’s 联发科press conference. In short, Snapdragon is light, thin, cool and
energy-efficient – most engineering samples displayed in this conference
are light as feather with no heat exhaust outlet.No specifications
available on these machines (naturally, most likely to be different, if
made to general market), however from form factor alone, ARM netbook is
something to look forward to. Continue below for more photos.

以下是大家对Snapdragon 855与Kirin 980的条件测量检验结果的观念:

  Nvidia Jetson stands for a series of computation processor boards from
Nvidia. The Jetson TK1, TX1 and TX2 models are all are carrying a Tegra
processor from Nvidia. Nvidia claims that it is an AI supercomputer on a
module, powered by NVIDIA Pascal architecture. Best of all, it packs
this performance into a small, power-efficient form factor that’s ideal
for intelligent edge devices like robots, drones, smart cameras, and
portable medical devices. It supports all the features of the Jetson TX1
module while enabling bigger, more complex deep neural networks. If you

笔者们精心的来深入分析一下竞争的情态,微软若让可同期帮助x86管理器与ARM架构的
“桌机版” OS,以及仅接济ARM架构管理器的Windows Phone
7并存,象征着日前微软是与Apple与谷歌(Google)走相反的发展大方向,纵然微软声称位在加州的这两大敌手也利用双脉并行的操作系统战略。Apple很醒目地保留Mac
OS X给笔记 /

[翻译:书嫚特][原作:Ross

95称霸PC市集来讲最足以打动Wintel架构的挑战。这新的咬合是由Android操作系统加上ARM架构的Computer,姑且称之为
“ARMdroid”
,它抓住了各家媒体好些个篇幅的简报,可说是大显神通。当中,最显著的莫过新兴的平板电脑如OPPOXoom和LG
G-Slate。但假诺IT商家们不鸟苹果阵营所谓「什么样设备就应当配特定操作系统」的调调,並且愿意把基于ARMdroid概念开采的产品设计成更就如现存小笔电的外形,那么就能够产出像Eee
Pad Slider那类的产品,假诺 “剽窃” 平板计算机(Tablet

Build Information and Tensorflow Version:

  • L4T 28.1 (JetPack 3.1)
  • CUDA 8.0
  • cuDNN 6.0

  • Tensorflow Version 1.3.0
  • Built with CUDA support

MTK公司在Snapdragon 855中定制的Adreno 640 GPU在麒麟980平台上征服了ARM
Mali-G76MP10 GPU。就算是Snapdragon 845中的Adreno 630
GPU也优化麒麟980的GPU。我们从没机遇测量试验真实游戏,但从这一个结果来看,Snapdragon
855应该是更加好的移动游戏平台。

Installing Step:

  1. <font color=red>First Step:</font> Download JetPack
    • You can download JetPack3.1(L4T 28.1) form
      https://developer.nvidia.com/embedded/jetpack.
    • If you are Chinese, it maybe download slowly, so I show you a
      BaiduPan which is other developer put it up. Link:
      https://pan.baidu.com/s/1o7Nfa10
      Password: r2mt.
  2. <font color=red>Second Step:</font> Run JetPack on
    your PC

    • Cd your file’s path.
      cd ~/Downloads
    • Set the file executable permission.
      chmod +x ./JetPack-L4T-3.1-linux-x64.run
    • Run it.
      ./JetPack-L4T-3.1-linux-x64.run
  3. <font color=red>Third Step:</font> Installing
    Interface

    • Read and watch it conscientiously. If it is no choice for you,
      you can click next no worry about it.
    • Full install or make your choice. As for me, I choosed no action
      OpenCV because this version is called OpenCV4Tegra and some
      libraries require different modules and such that require
      upstream OpenCV versions.
    ![](https://upload-images.jianshu.io/upload_images/9830587-8b92b3183a13185c.png)

    installface.png

-   Accept **all licenses**.
-   Select the **network layout**(I recommend you select the first
    way.).  

    ![](https://upload-images.jianshu.io/upload_images/9830587-d23dbdac14611b0a.png)

    002.png

-   Then you will select the network interface and it will show that
    all the **network card** in your PC. You can run the
    **`ifconfig`** command on your PC terminal, and choose the
    device which has IP net or is in your LAN. Such like this:  

    ![](https://upload-images.jianshu.io/upload_images/9830587-66f7f8c9aa995230.png)

    Network Device

-   So you need to choose the wlp4s0 device.(The picture is catch by
    Internet, not my PC show. You should make choice depending on
    your PC.)



    ![](https://upload-images.jianshu.io/upload_images/9830587-345ca456dd9257ec.png)

    003.png

-   Clicking the next, and you will obtain the interface from
    terminal where show you how to put your Jetson TX2 to force
    **USB Recovery Mode** and if you are ready, press the **Enter
    key**.
    1.  **Power off your device**, the best way you do is that
        shutdown your Jetson TX2 and remove the power adapter for 3
        seconds.
    2.  Connect **Your PC** up to **TX2** with **Micro-USB**.
    3.  **Power on your device**, and **immediately press and hold**
        the **RECOVERY** button(REC on your board), meanwhile press
        the **RESET**(RES on your board) button and release it. If
        you see the TX2 board flash it's light for a while, that
        means that you are successful in Recovery Mode.  

        ![](https://upload-images.jianshu.io/upload_images/9830587-2a0a8d188942f428.png)

        004.png

    4.  Also you can run `lsusb` in your PC terminal to show whether
        you are successful.(You can also skip this step.)  

        ![](https://upload-images.jianshu.io/upload_images/9830587-b8b7ced8966c8119.png)

        005.png
-   Installing Process will spend some time, then the Jetson TX2
    will **power on** and your PC will connect it by
    SSH(automatic).  

    ![](https://upload-images.jianshu.io/upload_images/9830587-d72b8121cc6d4110.png)

    006.png

-   Finish in installing and you can **remove all packages** about
    JetPack.

出于PC马克衡量系统特性,因此看到优质的Google Pixel 3 XL软件在QualcommSnapdragon 855参照设备上的属性略高于近乎AOSP软件也就相差为奇了。

1.Use GStreamer and OpenCV Capture the Image of Camera

2. Opening the Max performance of TX2

  • Jetson TX2 consists of a CPU and a GPU cluster. Dual – core CPU
    clusters composed of 2 processors and quad – core ARM Cortex-A57 in
    Denver, connected by a high-performance interconnect architectures.
  • Next I will list all modes of Jetson TX2 and the detail about it.

必赢电子游戏网址 14

mode of TX2

  • Check the mode Version:

    sudo nvpmodel -q –verbose
    
  • Open the Max Power:

    sudo nvpmodel -m 0
    
  • Show the Information of GPU:

    sudo tegrastats
    #If you see some cpus not opening, you can run like this:
    sudo su
    echo 1 > /sys/devices/system/cpu/cpu1/online
    
    #执行~/jetson_clocks.sh可以开启最大频率
    ~/jetson_clocks.sh
    

我们自然会测量试验新的Exynos 9820,但三星(Samsung)Galaxy
S10还不曾。大家不能够不等到4月技艺幸不辱命那或多或少。

Installation:

  • Download the sources and build OpenCV:

    git clone https://github.com/jetsonhacks/buildOpenCVTX2.git
    cd buildOpenCVTX2
    ./buildOpenCV.sh
    

    Note: If you need the OpenCV which is also working in
    python3, you should open the buildOpenCV.sh file and change it
    like this:

    Change the BUILD_opencv_python3=OFF to ON
    Also you can make the building in python2 OFF
    
  • CD your download path and make bulid:

    cd ~/opencv/build
    sudo make install
    
  • Check your library vaild:

    import cv2
    cv2.__version__

3.Build OpenCV:

必赢电子游戏网址 15

Background:

  JetPack can install a CPU and GPU accelerated version of the OpenCV
libraries, called OpenCV4Tegra, on the Jetson. OpenCV4Tegra is version
2.4.13 as of this writing. This is great for many applications,
especially when you are writing your own apps. However, some libraries
require different modules and such that require upstream OpenCV
versions.
