I don't think this would be usable on such a small FPGA. It will probably fill 
most of the device and you will have no more room for a CPU etc.

Check out the Spartan 3A starter kit port.

You need to compile vpi_images.c as a PLI module and load it into Modelsim. I 
don't know how to do this with this simulator, but if you use GPL Cver the 
Makefile will compile the module and run the simulator automatically for you.
