Hi Sunny yang,

Apologize in advance since I’m not the expert in PCIe application, so I won't be much of a help here. Are you using your own software driver in the CPU (RP) to communicate and send the data to the Cyclone IV (EP)? Or are you using the example design from AN456 to test the PCIe performance in Cyclone IV device?

I that suggest that you re-post this question in the IP Discussion forum in order to get the right help among the PCIe and IP communities or users. Refer to the following link:
