I have a text file with 10^9 bits that I would like to introduce as my pattern. Is it possible with a dual-port ram introduce that number of bits? How would I be able to read the text file and introduce them as my input bitstream?

10^9 = 1Gbit, is about 1000x too big for on-chip RAM. However, it is only 128MB which is not bad for DDR memory. Ultimately it depends on what your hardware has to offer.
Regarding using Avalon-MM/Avalon-ST RAM components, I have recently updated a tutorial that contains these components;
