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
