The AXI Streaming FIFO allows memory mapped access to a AXI Streaming interface. The core can be used to interface to the AXI Ethernet without the need to use DMA. The principal operation of this core allows the write or read of data packets to or from a device without any concern over ...

This IP core has read and write AXI-Stream FIFOs, the contents of which can be accessed from the AXI4 memory-mapped interface. This is useful for transferring data from a processor into the FPGA fabric. The driver creates a character device that can be read/written to with standard open/...
register/FIFO. This capability is provided in both manual and automatic slave select modes. As an example, during the page read command, the command, address, and number of data beats in the DTR must be set equal to the same number of data bytes intended to be read by the SPI memory....

The size of the FIFOs can be configured by setting the CMD_FIFO_ADDRESS_WIDTH, SDO_FIFO_ADDRESS_WIDTH and SDI_FIFO_ADDRESS_WIDTH parameters. One end of the FIFOs are connected to a memory-mapped register and can be accessed via the AXI-Lite interface. The other end is di...
To generate an example stand-alone application for these boards, the Vitis build script makes a local copy of the driver for the AXI Memory Mapped to PCIe Gen2 IP with a few small modifications to make it work with the Gen3 core. If you use or modify these applications, be aware that...
When the data phase TD(s) finish, a status phase TD can be invoked that reads some memory mapped status information from the peripheral and copies it to a location in system memory specified by the CPU for later inspection. Multiple sets of configuration, data, and status phase “subchains...
