  • The AXI specifications describe an interface between a single AXI master and a single AXI slave, representing IP cores that exchange information with each other. Memory mapped AXI masters and slaves can be connected together using a structure called an Interconnect block.
  • MicroZed Chronicles: Verifying AXI Peripherals. The designs we implement in Vivado often use AXI interfaces. These might be AXI Lite for configuration and control, AXI Memory Mapped for high-speed memory mapped transfer, or AXI Stream for high-bandwidth streams. These interfaces can be complex to verify, ensuring we get the protocol implemented correctly for bus transactions can present a challenge on its own.
  • The Digital Blocks DB-SPI-FLASH-CTRL is a Serial Peripheral Interface (SPI) Controller Verilog IP Core supporting access to Single/Dual/Quad SPI Flash Memory devices by way of Boot, Execute-in-Place (XIP), Processor Memory-Mapped IO, or optional DMA.

The AXI Direct Memory Access (AXI DMA) IP provides high-bandwidth direct memory access between the AXI4 memory mapped and AXI4-Stream-type target peripherals.
Dec 16, 2013 · 2. Secondly, about your last question. Any e500* core boots/start up by default with 4KB window in the TLB (virtual space 0xFFFF_F000 mapped to physical space 0xFFFF_F000 - this is 1:1 as you can simply observe). So, the u-boot just use this memory map at start-up.

Nov 15, 2016 · Let me tell you the settings for the project. In QSys, the first Frame Reader was mapped to 0x0000_0100-0x0000_017f on h2f_lw_axi_master. After adding the second one I mapped it to 0x0000_0180-0x0000_01ff. I generated the QSys system and after compiling the project in Quartus generated new hps_0.h header file.
Memory mapped I/O is lightening speed since it incorporates memory addressing (which is super fast for the RAM), hence graphics type computer use just memory mapping for the I/O to get the speed. I/O mapped I/O is assigned for slow ports e.g. rs232, or the parallel port, and uses the IN OUT commands.

Mar 14, 2020 · All three of my AXI DMA algorithms have some capability for aborting transactions. This includes my AXI stream to memory core, my AXI memory to stream core, and my AXI DMA core. Unlike the major vendor cores, these three are all open source. Each contains an AXI-Lite control port, and a full memory mapped AXI4 master port.
The PCIe based MATLAB as AXI Master feature provides an AXI Master object that can be used to access any memory mapped location in the FPGA. This example shows how to integrate PCIe based MATLAB as AXI Master into a Xilinx Vivado project, and read or write to the DDR memory using MATLAB.
