在Block Design中实例化自定义设计AXI主机接口驱动(AXI_tansaction.v)、AXI从机接口(MPSoC-IP),并使用AXI_Interconnect-IP进行连接,通过地址定义,将AXI接口指向MPSoC端的DDR4存储器,添加axi_protocol_checker-IP以及ila-IP对通信过程中的关键信号进行抓取和监测; 实例化BD、外部数据激励以及结果统计模块。 3.2 写过程...
Features ● Supports AXI3, AXI4, and AXI4-lite interfaces ● Supports N-to-1, 1-to-N, N-to-M (shared access mode) interconnect ● Supports 3 arbitration modes — Fixed priority — Round robin 1 — Round robin 2 ● Verilog HDL RTL and simulation testbench New in v2022.2 Added pipe...
AXI lite nonblocking crossbar interconnect with parametrizable data and address interface widths and master and slave interface counts. Read interface only. Fully nonblocking with completely separate read and write paths; FIFO-based transaction ordering protection logic; and per-port address decode, admis...

AXI interconnect IP是一个功能强大的IP,它能管理多个AXI接口的IP。用户如果用到多个AXI IP,那么只需PS将M_AXI_GP0引脚连接到AXI interconnect Ip的SO0_AXI引脚,再将AXI interconnect ip的输出分别连接到每个AXI IP的S_AXI引脚即可,省去了多个AXI互联的管理问题。Processor System Reset IP为其他IP提供复位信号。
It supports data bit width conversion. The axi_interconnect.v module supports software-generated configuration. Defects: The current version does not support out-of-order bursts. Auxiliary control signals such as cache, lock, and QoS do not support independent configuration for each interface....
Vitis HLS专门提供了stream库,若函数形参为stream类型,那么默认情形下Vitis HLS会将其映射为ap_fifo接口,但也可以通过pragma interface将其指定为axis接口。仍以上一篇文章所阐述的累加器为例,如下图所示。代码第13行定义了输入数据结构体,该结构体内包含两个元素,一个为实际传输的数据,另一个则是模拟AXI4 Stream的...
8)点击“Optimize Routing”,可以优化布局,同时可以看到多了两个模块,一个是Processor System Reset模块,为同步复位模块,提供同一时钟域的复位信号。AXI Interconnect模块为AXI总线互联模块,用于AXI模块的交叉互联。 在这个应用中,我们可以看到用到了ZYNQ的HPM0_LPD口,此接口用于访问PL端数据,大部分应用中是为了配置PL...
为便于说明,我们用一个较为简单的算法——累加运算为例。假设每帧数据长度为4,累加运算就是求取这4个数据的和,如下图所示。不同颜色代表不同帧的数据。可以发现数据是顺序流动的,同样累加器访问(读取)数据的方向也是顺序进行的。这符合AXI4 Stream接口的要求。
