Data Transfer between HPS and FPGA on Altera De1-soc board

My project is to transfer data between Hps and Fpga on altera De1 soc board. Fpga side there will be Sdram and from the hps we should be able to read and write the data. The data transfer will be done with through AXI bridges and this hardware part can be designed using Quartus 2 Qsys. Hps can be programmed using C language using altera de-5. Ultimate goal is to transferring data. I am new to this field and don't know exactly what to do. I have created Qsys part( with sdram controller, pll , hps i.e cyclone v , jtag uart) I have successfully created the connections with the master slave AXI Avalon interface. Now don't know how to proceed further.
