Hi all,
Absolutely new here, so please bear with me ;-)
I'm trying to built a board which has 2-4 8255 chips attached to the
pci bus. My idea is to get the Memec Spartan 2 board for it, and
make a small add-on board with the 8255s (and other stuff). I thought
about using the Opencores PCI Bridge for it.
This is a little silly. An 8255 merely has I/O's -- you would be
better off just using the I/O's of the FPGA for this function. Is
this a school project?
So, the question are
...
a.) What problems should I expect ?
b.) how difficult would that be ? (boards & layouts are not a
problem)
c.) are there still enough resources in the spartan II left (with the pci
bridge & control for the 8255s), to add a DMA engine to it
?
d.) Anybody out here did something like this ?
e.) where else to look for any input/links ?
cheers & thanks in advance
