Xilinx Vitis-AI - Who is using this framework ?

albertabeef

Hello all,

 

I have been fairly busy creating designs that make use of Vitis-AI, Xilinx's development framework for AI.

 

I wanted to know how many users are using Vitis-AI ?

 

What type of project or tutorial would you like to see based on Vitis-AI ?

 

Regards,

 

Mario Bergeron.

  • Hi Mario,

     

    I'm surprised that you haven't gotten a lot of responses to this post as I know that there are a lot of Xilinx users in the E14 community.

     

    I've really appreciated the Vitis-AI posts that you've done on Hackster.  I've been taking a break from the Xilinx FPGAs and been focusing on TinyML, so I haven't tried your latest Vitis-AI 1.3 stuff yet.

     

    I've had problems using the IP cameras with the VCU and GStreamer on the UtraZed-EV.  I'll probably get back to working on this later this summer.  Have you done much with the VCU?  Has anyone replaced Jason Moss after he left Avnet to go to Xilinx?  I think he was the resident expert.  It would be great to see projects integrating the VCU and GPU.

    HI Ralph,

     

    Always appreciate your input and feedback.

    We are still working on a path forward to fill the void Jason left.  I think he was a man of many hats and we are working towards some new VCU designs across a few resources.

    He was a man of many hats and talents!

     

    Regardless, the new designs are being targeted for the 2020.2 release, which as of this post is not official yet...so buyer beware!  The 2020.2 branch is almost stable.  As of this exact post, the build scripts for those projects are stable enough for validation testing.

     

    For those in the future:

    https://github.com/avnet/

     

    Grab the petalinux, hdl, bdf, repositories.  Then checkout the 2020.2 branch (or in the future, the appropriate tag).  In the petalinux/scripts folder, you should be able to target the make_uz7ev_evcc_hdmi_v.sh or the make_uz7ev_evcc_quadcam_h_v.sh build scripts.  Once completed and the files are put on an SDCARD for testing, I have been told there are scripts that can be run in /home/root/ that setup everything for the tests.

     

    The latter requiring the Quadcam FMC kit.  The former being essentially the VCU design that Jason worked on (on the Xterra2 server).  The design has been extended to include HDMI as inputs/outputs, but still has the original webcam->RTSP capabilities.  Again, not validation tested at this time, so any support will be very limited until this is released.

    Thanks Dan.  Helpful as always.  I may actually get around to trying out the HDMI with the VCU image.   Any preview as to what functionality you'll have in the new VCU designs?

     

    Probably be bugging you guys mid-summer when I run into problems...

    Hi Ralph,

     

    For now, it just spins up the VCU.

    4K HDMI RX -> VCU Enc -> VCU dec -> 4K HDMI TX

    4K HDMI RX -> VCU Enc -> file

    file -> VCU dec -> 4K HDMI TX

    Quadcam -> VCU Enc -> VCU dec -> 4K HDMI TX

    webcam -> VCU Enc -> RTSP

     

    I am working towards a webinar on this, so anything in particular you think you'd like to see, let me know and I'll see if that will fit in with the messaging on the webinar.
