• Primary DMA Control
    • File: Stage1/PrimaryDMAControl/PrimaryDMAControl.vhd
    • Entity: PrimaryDMAControl
    • Status: Working
    • Description: The Primary DMA Control sets up a DMA of the PCIe core. It transfers the data from the buffer memory to the host memory. The Free Page FIFO provides the address of the next free page of memory in the host system. Information about the packet in the buffer memory is read from the Used FIFO (via the Used FIFO Arbitration). Each packet in the buffer memory is transferred to a separate page in the host memory. On completion of the DMA some information is written to the DMA done FIFO giving a summary of the transfer.
