Honored ContributorYes this is the part, and you also need to include those functions (ncpalloc/ncpfree) in your project. IIRC they are in a file called optimisations.c in the example project. Those functions are the ones that will take care of allocating the buffers in the on-chip memory, and will set them as uncached (either by setting the address MSB to 1 or by using the more futureproof alt_remap_uncached() function).
I don't think there is a ready made checksum IP available, at least not on the Altera website. You could check Opencores.org, but I don't think it would be very complicated to do it yourself.
