Addresses in the range of 0 - (4 * transferSize) will # be used for this test when the PCIe DMA core is setup for memory # mapped transaction. transferSize=1024 WebMar 13, 2024 · First off, there are two primary modes of the driver, AXI-Memory Mapped (AXI-MM) and AXI-Streaming (AXI-ST). For my particular application, I require AXI-ST, since data will continuously be flowing from the device. The driver is written to take advantage of scatter-gather lists.
