Proper DMA-based communication from the FPGA to the host requires some awareness of the specification's details, but it's otherwise fairly straightforward in the sense that packets are formed, dispatched and assured to arrive in the order they were sent. The PCIe Endpoint drives the PCIe slot on the FPGA board. It is important to note that if the host computer cannot read data from its RAM buffer fast enough, the DMA FIFO eventually fills up and the DMA to Host FIFO times out. Before the GPU can read from a DMA buffer, the display miniport driver must page-lock the DMA buffer and map the DMA buffer through an aperture. The FPGA targets that support DMA include a fixed number of DMA channels available for transferring data between the FPGA VI and the host VI.
