If I understand it correctly, PCIe has independent read and write paths for each channel. Does that mean we could actually be doing a DMA upload and a DMA download at the same time?
If so, under what circumstances might it be useful to us to be doing transfers in both directions at the same time? Recall that we would prefer to shadow textures in host memory, so we never have to download images unless the GPU has drawn to something. I can think of a few non-graphics situations where this would be useful. If the FPGA had some logic in it to do something like [EMAIL PROTECTED], it would be nice to upload a new chunk and download the results from the last one at the same time.
