PYNQ: PYTHON PRODUCTIVITY

Is there a good tutorial for using Vitis vision library on PYNQ?

#1

I want to create an Overlay from the vitis vision library for a project and searching for a good starting tutorial. Do you know one or where I have to look?

The only clue what I found is this:
https://pynq.readthedocs.io/en/v2.5.1/pynq_alveo.html?highlight=vitis#programming-the-device

I also found how to create an Overlay at the [PYNQ-ComputerVision Repository] but it uses the Xilinx SDx tools and not Vitis (https://github.com/Xilinx/PYNQ-ComputerVision/blob/master/overlays/README.md).

I am also not sure what a should use…

Edit 1: I also found on hackster this, but it uses the xfOpenCV instead of Vitis Vision Library: https://www.hackster.io/dhq/accelerating-image-processing-with-ultra96-caebe6

You can check https://github.com/Xilinx/PYNQ-HelloWorld

For z1/z2/zcu104, we actually got the HLS IP from Vitis library and used Vitis to build the entire design. You can also check the notebook to see how we interact with buffers / dma / etc.

Thank you very much for your reply @rock . :heart: I really appreciate your help! And I will check it out.

May I ask your for your design flow? Because I looked into the GitHub Page and Linux was used. Unfortunately I only have installed Vitis Platform on my Windows 10 Machine. Additionally I have an Virtual Machine that runs Vivado 2018.3 and the SDx Devoloper environment.

Do you think I can I also run the examples on my Windows 10 Machine ?

You can use the vagrant flow to setup ubuntu VM and then build image from there.
