1.4.1 AXI MasterIF

A typical PCIe application interface uses an AXI master interface to respond to data read requests and an AXI slave interface to initiate requests. The AXI master performs the following functions:

• Conveys PCIe read and write transactions to the fabric in the form of AXI4 reads and writes.
• Accesses the DMA controller through the bridge and issues reads and writes that allow data pulled from the fabric to be sent over PCIe and data pulled from the PCIe to be written out to the fabric.
