But since you a pressed for time, maybe you might prefer to just instantiate PIO in/out modules and connect your new hardware together in the top level. Then the software is simply a few library routines that manipulate the PIO hardware as your component expects. The examples are here: http://www.altera.com/support/examples/exm-list.jsp?cat=embedded The checksum accelerator is probably as good a starting point as any.
