DE0-Nano-SoC : Sending data from FPGA to HPS

Hi,

Does anyone know how to send a 32-bit word from the FPGA to the HPS?

Details:

I have created an IP core that receives four bytes of data and concatenates them in a 32-bit word. The words are generated at approximately 1 MHz and I need send them to the HPS so that they can be grouped in a UDP frame.

I am new to Quartus and Platform Designer and my biggest problem is how to connect the FPGA to the processor.

Please, any piece of advice would be appreciated.
