Hi rsefton. I'm not skill with pcie.

Can you explain me if i must use the avalonst or avalonmm examples?

And can you explain me if for my project is better

to use a internal memory example or a external sdram

example?

The idea is:

1) the board generates 64kB of data

2) the board send with dma 64kB to sdram of PC

3)the board checks if. Dma is complete (is possible?)

4)the board send interrupt to pc.

5)the pc read 64kB of data from pc sdram.

6) the pc executes a dma write to board for inform it to send another 64kB of data
