Transfferring data from PS to PL

Question

I am using Zynq7000. I have my data in the Processor System (PS) obtained from the PC through UART and stored into an array. How can I transfer these data from the PS to the FPGA (PL)? I saw some resources only said to use an AXI interface, but I have no idea how to achieve that.

I am very new to FPGA. Please help me with some tutorial or simple example like transferring an 8 bit data from PS to PL.

Thank you!

Hello,

There are several ways to transfer data between the PS and PL portions of the Zynq device. The Avnet Developing Zynq HW and SW Speedway workshops have examples of creating and using AXI based PL peripherals. There are hands on labs for both the ZedBoard and MicroZed boards. You can download these here:

Adam Taylor has an excellent blog, the MicroZed Chronicals, on how to implement applications using the Zynq device.There is a section, starting with issue 21, that details creating a PL based peripheral:
