CNN using HLS

I am pleased to announce the release of the code for the article “How to Implement a Convolutional Neural Network Using High-Level Synthesis”.

Synopsis

The previous article discussed three main aspects:

  1. The used approach to implement a Convolutional Neural Network (CNN)
  2. The elements that I took into account when choosing the neural network architecture
  3. The specific High-Level Synthesis constructs that helped to achieve the targeted performance.

Download

Now you can download the code from GitHub.
The GIT repository contains:

  • The CNN implementation
  • The python codes used for training
  • Modules for each type of layer (convolutional, pooling and fully connected) used for development and testing
  • Short guide on how to set up and run the code

The CNN code is provided as an OpenSource implementation under Apache License 2.0.
I welcome your feedback!

Sorry, but I do not see the python codes used for training.

Hello Sergiu Duda,

Please tell me if you can post the full version of your diploma thesis for review on github, or is it forbidden?

Thank you in advance.

hello
,thanks for usefull information.I want to know whats the input of your code because I cant to simulate it with vivado hls , and how can I simulate it with vivado?can i add synthesis vhdl code to vivado for simulating it?would you mind help me?

    Hi Anahita,

    The image is sent as an input to the first CONV layer in nnet.cpp at line 333.

    To simulate it with Vivado, you will first need to export the RTL. For this you have two options:
    * use the button in VIvado HLS which is near the Synthesis button
    * Run a .tcl command: export_design -flow syn -rtl vhdl -format ip_catalog

    Then you need to import the IP in Vivado, through the IP catalog. After this step is done, you can instantiate the IP as any other Xilinx IPs in the Block Design.

    Regards,
    Sergiu
