import data into Nios

Hi, 

 

Could anyone tell me that what is the fastest way to import data to Nios? 

 

For instance, I have a verilog module and the output is  

 

output [7:0] dout; 

output source_valid; 

 

with a clock rate of 25MHz. Is there any way to import these data into Nios system without loss? Apparently the pio itself can not fulfill this task. 

 

Thanks
