Memory-Mapped Protocols: In memory-mapped protocols (AXI3, AXI4, and AXI4-Lite), all transactions involve the concept of transferring a target address within a system memory space and data. AXI_Stream不属于存储器映射。 5.AXI4的优势 AXI的优势 生产力: 灵活性:AXI4(支持突发256)和AXI4_lite(...
AXI4(AXI4-Full): 满足高性能内存映射(memory-mapped)需求。支持256长度突发(burst)传输。 AXI4-Lite: 对于简单的、低吞吐量的内存映射通信(例如,与控制寄存器和状态寄存器之间的通信)。不可突发传输。 AXI4-Stream: 用于高速流数据。不需要地址,允许无限的数据突发大小。 AXI4的好处: 生产力:统一协议,减少学习...
AXI4 是一种高性能memory-mapped总线,AXI4-Lite是一只简单的、低通量的memory-mapped 总线,而 AXI4-Stream 可以传输高速数据流。从字面意思去理解,AXI4-Lite是AXI4的轻量版。这里保留了memory-mapped的写法,主要是为了与AXI4-Stream区分开。 memory-mapped 可以这样去理解,假设有master A , 和 slave B, A与B...
AXI4-Stream:用于高速流传输数据。 一般情况下,AXI4-Full总线也被直接简称为AXI4总线。AXI4-Full、AXI4-Lite都是内存映射型总线(需要地址),其是多主多从的拓扑结构,可通过Interconnect(AXI4交换设备)来进行互联。具体到XILINX的AXI4应用,一般使用这两个IP来进行多主多从的AXI接口互联:AXI Interconnect(一般使用这...
一、AXI总线概述1.三种AXI总线AXI4:(For high-performance memory-mapped requirements.)主要面向高性能地址映射通信的需求,是面向地址映射的接口,允许最大 256 轮的数据突发传输;AXI4-Lite:(For simple, low-throughput memory-mapped communication )是一个轻量级的地址映射单次传 ...
AXI4:(For high-performance memory-mapped requirements.)主要面向高性能地址映射通信的需求,是面向地址映射的接口,允许最大256轮的数据突发传输; AXI4-Lite:(For simple, low-throughput memory-mapped communication)是一个轻量级的地址映射单次传输接口,占用很少的逻辑单元。
Stream模式下影响很明显，在AXI Stream模式下选择多通道，可以连接不同的数据源。在AXI Memory Mapped...
AXI4-Lite memory-mapped ports are used to control the contents of the Look-up engines and to configure, read, and write to externs. Each Vitis Networking P4 instance has a single AXI4-Lite slave interface. An AXI4-Lite crossbar is created within Vitis Ne

AXI4-Lite:(For simple, low-throughput memory-mapped communication )是一个轻量级的地址映射单次传输接口,占用很少的逻辑单元。 AXI4-Stream:(For high-speed streaming data.)面向高速流数据传输;去掉了地址项,允许无限制的数据突发传输规模。 由于AXI4和AXI4-Lite信号大部分一样,以下只介绍AXI4信号.另外对于AX...
