AXI是Interface还是Bus? AXI全称Advanced eXtensibleInterface,是Xilinx从6系列的FPGA开始引入的一种接口协议,主要描述了主设备和从设备之间的数据传输方式。该协议是AMBA3.0(Advanced Microcontroller Bus Architecture)中最重要的部分,是一种面向高性能、高带宽、低延迟的片内接口协议。AMBA4.0将其修改升级为AXI4.0,如下图...
Xilinx的工程力。 PS:此处我读数据是通过AXI的,但和直接读memory是一个道理。 为了优化性能,必须得通过port widening来提升IO速度。 对于HLS function,可以通过一定的逻辑,生成可widen的AXI interface,这里略去。 如果是对于此处直接读memory的情况,一个道理,可以通过读一个更大端口的memory加大并行度。e.g,memory ...
The AXI4-Interface Read block, using the central interconnect of the processing system, provides simple memory-mapped communication with the IP core on the FPGA. This block is best suited for low-throughput communication, such as inspecting status, state, or control registers. ...

[BD 41-968] AXI interface port /axi_lite4 is not associated to any clock port. It may not work correctly. Please update ASSOCIATED_BUSIF parameter of a clock port to include this interface port. 在块设计中,时钟、复位、bus是分开的,需要把时钟复位引出。

under this top level svt_axi_if interface instance. 有两种模式连接时钟,即svt_axi_system_configuration::common_clock_mode为0或1;为1时,只需要把时钟连接到axi_if即可;为0时,需要master和slave分别连接各自的时钟; 1. If you want to use a common clock for all the master and slave port interfaces...
The register interface uses an AXI4-Lite interface, which was selected because of its simplicity. The following figures show typical AXI4-Lite write and read transaction timings. Figure 1. AXI4-Lite Write Timing Diagram Figure 2. AXI4-Lite Read Timing Di
Hello. I have a question regarding the use of AXI interconnect in Qsys 11.1. I have the VHDL component, which must communicate with NIOS
Solved: How can i use axi interface in hls codes.i can able to use avalon stream and memory avalon memory mapped interfaces but not axi stream and
