Write Data in DDR Memory With PS and Read Them Through PL

Former Member

Hi everyone !
I'm new in working on Zedboard. I have a project that I should write some shapes like line, circle etc in C code and show them on VGA output. So, I decided to use DDR memory and write data on DDR memory, then read them from a costume VGA controller in PL and show them on VGA port.
Is there any tutorial that could help me?
If you have a better way for me to do this, it will be great that you show me ?!

I am really in hurry, so please help me !!

    Hi toofan,

    If you have an HDL VGA controller you might be able to bolt it up to the Xilinx AXI VDMA to pipe the frame buffer contents from DDR3 into the PL using the HP AXI interconnects.

    In fact this is what we do in order to send information to the PL for our Zed display kit.  We also have an X-fest topic which covers this type of design called Building Blocks for Enhancing User Interfaces so if X-fest is coming to your area soon, you might want to look into that technical training.

    Take a look at the Standalone tutorials that we have for our display kits because what we did sounds very similar to what you are looking to do:
