Forum général.cherche-matériel FPGA and CPU communication

Hello,

I am completely newbie about FPGA and CPU communication.
I have a CPU and FPGA (Xilinx board) .
I want to make my FPGA and CPU communicating, to send data from the CPU to the FPGA and from FPGA to CPU via Axi bus or PCIexpress…
I tried to make research on internet but I am completely lost and I don’t know from where to start.
Do have any advices? Any documentations ? Any links ?

Thank you,
