data transfer from fpga to hps

Dear all,

i am using Altera SOC (Cyclone V) development board for my project.

This board is receiving data on its GPIO (which is connected to FPGA side) at the rate of 27 MHz. It is continuous stream.

I want this data to be available to ARM processor so that i will write c code to access this data and modify it and send it over ethernet.

I am requesting help for how to access this data from c code? i have read that there are FPGA-to-HPS bridge through which data can be passed from FPGA to HPS. But in detail i am unable to figure it out this. Requesting for any design example or any links.

Thank in advance

    Can some one please reply to this post? I would like to know how to do this as well. We need this for our project.

    Has anyone made progress with this? I need to do it too. I only need to transfer four bytes at low speed. Chapter 5 of the Altera HPS documentation describes the three interfaces but now how to actually do it. Rocketboards.org have a couple reference designs that might help.
