s_axi_BUS_A is our AXI4-Lite interface: By the end of this tutorial, you will Understand the basics of creating an AXI4-Lite interface in Vitis HLS. Learn about pragmas in Vitis HLS, which define the AXI interface being used. Opening the AXI-Lite Example Design An example design ...
A full instructional series for all aspect of the AXI4 Bus protocol, including AXI4 Stream, AXI4-Lite, and AXI4. Each flavor of AXI4 has a bus flow, handshake, and signal requirements described in detail. An example implementation for a Master and Slave in each of the subsets of AXI4...
Double-click on the AXI_Sniffer.v file in the Sources window to open the file in the text editor We first need to declare the ports of the IP. We need an AXI4-Lite interface. As per the AMBA® AXI™ and ACE™ Protocol Specification available from the ARM website (link), these...
As with any project, I started off simple and just looked atAXI-lite. Unlike the full AXI protocol, AXI-lite doesn’t have nearly as many signals to it, and so it was fairly easy to work with. I began simply with thefour basic bus propertiesI had learned to use when working withWis...
(exceptAXI4-Stream) and Lite protocol and can be selected using a parameter. The width of the AXI data bus is customizable. This IP can drive anyAXI4-Liteor Memory-Mapped Slave directly. It can also be connected as master to the interconnect. Run-time interaction with...
This article introduced the AXI interconnect, a digital logic block that allows multiple AXI masters to communicate with multiple AXI slaves. AMBA Revision 3.0 specifically left the details of interconnects undefined to keep the AXI protocol flexible and extensible. ...
AMBA 4 AXI4-Stream Protocol Specification:这个是 ARM 讲解 AXI-Stream 的官方手册,需要注意的是 Xilinx 的 IP 核在 Stream 部分与 AMBA 的协议有一点区别。 下面给出一些Xilinx官网的Tutorial,这些tutorial都是博客形式的,可以使用这些博客中提供的工程文件在Vivado中仿真进一步理解协议的内涵。
Fig 1. A basic AXI bus structure One of the most popularCPUs in the embedded sub-chip IP market is theARM. WhileRISC-Vmay well giveARMa run for their money, much of the industry has already standardized around a set ofARMbus protocol standards drawn from theAMBA bus protocol set. Of ...
