The Xilinx ® DMA/Bridge Subsystem for PCI Express ® (PCIe ®) implements a high performance, configurable Scatter Gather DMA for use with the PCI Express ® 2. - DMA engine frees up CPU resources from data streaming, it helps to improve the overall system performance. If this step is performed, the performance highly depends on software and driver design on PC side. We’ll use the Xilinx DMA engine IP core and we’ll connect it to the processor memory. Hello,We have design a Xilinx Artix7 board connected to a PC with an ethernet port. In this tutorial, I’ll write about how to add a DMA engine into your design and how to connect it up to a data producer/consumer. /s/Adding/Add/ Please descibe the dmaengines here so people can know what to expect. The Zynq-7000 family processor block includes an eight-channel PL330 DMA controller that you can use to significantly improve throughput between your custom hardware peripherals and external memory. LogiCORE IP AXI DMA v6. Enable interrupts if chose to use interrupt mode. 0) for some of my projects and to my no surprise found Xilinx AXI-DMA not working again.
