Web# Size of PCIe DMA transfers that will be used for this test. # Make sure valid addresses exist in the FPGA when modifying this # variable. 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.

For this purpose, a special chip, named DMA controller, is used to control all activities and synchronization of data. As result, compare to other data transfer techniques, DMA is much faster. lee\u0027s chicken findlay menu
