Key Features in JetPack


TensorRT is a high performance deep learning inference runtime for image classification, segmentation, and object detection neural networks. It speeds up deep learning inference as well as reducing the runtime memory footprint for convolutional and deconv neural networks.

JetPack 3.2 Developer Preview highlight:

  • Support for TensorFlow models
  • Up to 15% perf/W improvement for DL applications

CUDA Deep Neural Network library provides high-performance primitives for deep learning frameworks. It includes support for convolutions, activation functions and tensor transformations.

JetPack 3.2 Developer Preview highlight:

  • Grouped convolution without any API changes
  • Support new CTC Loss Layer for RNNs

VisionWorks is a software development package for Computer Vision (CV) and image processing. It Includes VPI (Vision Programming Interface), a set of optimized CV primitives for use by CUDA developers. The NVX library enables direct access to VPI, and the OVX library enables indirect access to VPI via OpenVX framework.

JetPack 3.2 Developer Preview highlight:

  • Moves to upstream OpenCV 3.3.1, including neon acceleration and multithreading

CUDA Toolkit provides a comprehensive development environment for C and C++ developers building. GPU-accelerated applications. The toolkit includes a compiler for NVIDIA GPUs, math libraries, and tools for debugging and optimizing the performance of your applications.

JetPack 3.2 Developer Preview introduces CUDA 9 with these highlights

  • Fine grain control for synchronization and memory sharing control with EGLImage and EGLSync
  • EGLStream Support on x86: seemless development on x86 for Jetson deployment
  • NVRTC runtime compilation library for CUDA C++
Multimedia API

The Jetson Multimedia API package provides low level APIs for flexible application development.

Camera application API: libargus offers a low-level frame-synchronous API for camera applications, with per frame camera parameter control, multiple (including synchronized) camera support, and EGL stream outputs. RAW output CSI cameras needing ISP can be used with either libargus or GStreamer plugin. In either case, the V4L2 media-controller sensor driver API is used.

Sensor driver API: V4L2 API enables video decode, encode, format conversion and scaling functionality. V4L2 for encode opens up many features like bit rate control, quality presets, low latency encode, temporal tradeoff, motion vector maps, and more.

JetPack 3.2 Developer Preview highlights:

  • Buffer rotation and cropping
  • Picture-in-picture support, demonstrated with new multi-camera sample

The NVIDIA® Tegra® Linux Driver Package supports development on the Jetson Platform.

Development Tools

NVIDIA System Profiler is a multi-core CPU PC sampling profiler that provides an interactive view of captured profiling data, helping improve overall application performance./p>

Tegra Graphics Debugger is a console-grade tool that allows developers to debug and profile OpenGL ES 2.0-3.2, OpenGL 4.3-4.6, enabling developers to get the most out of the Jetson Platform.

JetPack 3.2 Developer Preview highlights:

  • Tegra Graphics Debugger 2.5
    • The Batch Histogram view can be used to visualize draw call buckets, based on primitive count
    • Added theming support for the Tegra Graphics Debugger GUI
    • Can now view query object results and conditional rendering results in the API Inspector


  • JetPack 3.1 requires Ubuntu 14.04 on your host PC
  • JetPack 3.2 Developer Preview supports Ubuntu 16.04 on your host PC
    • Ubuntu 14.04 on your host PC will also work, except OpenCV and VisionWorks will be unavailable for installation on that host PC
