Write from FPGA to external processor's memory

Hi, I am creating a design that implements a counter (Qsys interval timer) in FPGA and to write these counter values to external processor's memory via PCIe. I memory mapped the counter to PCIe...

Hi Dave,

Thank you very much for your feedback.

Is host-processor considered to be Avalon-MM master in this case ?

The PCIe should see the address space on the host processor in order to write to that reserved memory space. Can you tell me if PCIe to host processor address mapping is as per "PCI Express-to-Avalon-MM Address Translation" as mentioned in the Altera's PCIe guide ?

Thanks,

Manish
