Hi all,

I'm getting started with the examples, specifically with the hello_world
from the intel-fpga-bbb
<https://github.com/OPAE/intel-fpga-bbb/tree/master/samples/tutorial/01_hel=
lo_world>
repository.
Everything works just fine but I was wondering if it is possible for me to
access the Main Memory (Not IO) from the FPGA using the CCI protocol.

I have an rtl to sum two vectors, so my idea was to provide the addresses
for those two vectors from the software application, allocated in General
Purpose Memory. This way, ideally, the FPGA should be able to access those
vectors without having a shared buffer (MMIO).

Is it possible to do this, maybe using some MPF extension? In case this is
not feasible, I should allocate a shared buffer in MMIO space and then
comunicate the vectors through that buffer, right?

Thanks!
