AXI:Advanced eXtensible Interface,用于高性能,高带宽,低延迟的片内总线 AXI简介 AXI(Advanced eXtensible Interface,高级拓展接口)接口协议是AMBA(Advanced Microcontroller Bus Architecture,高级微控制器总线架构) 的一部分,AXI于2003年第一次提出,在2010年升级为AXI4。 AXI总线有三个类型: AXI4(AXI4-FULL),用...
In the AHB protocol every transfer comes with an address value on HADDR. As you already know how the address will change because of what is signalled on HBURST, HTRANS and HSIZE, the HADDR information for all transfers after the start of the burst could be considered unnecessary as the targ...
This paper gives a brief description of various on-chip bus protocols such as the Advanced Microcontroller Bus Architecture (AMBA) Advanced High-Performance bus (AHB) and Advanced Extensible Interface (AXI), Wishbone Bus, Open Core Protocol (OCP) and CoreConnect Bus. It gives a brief introduction...
AXI4.0总线协议简介Advanced eXtensible Interface (AXI) protocol是有ARM公司提出的高级可扩展接口协议,在AMBA4.0中将其修改升级为AXI4.0。主要包括AXI4.0、AXI4.0-lite、ACE4.0、AXI4.0-stream这四种。Xilinx从Spartan-6和Virtex-6设备开始,引入了AXI协议,因为其优点有很多,就不罗嗦了。

AXI 协议支持无序事务完成和多个未完成地址的发送(如何理解??The AXI protocol enables out-of-order transaction completion and the issuing of multiple outstanding addresses.)。 这些特性能够实现高性能互连,最大限度地提高数据吞吐量和系统效率。 ID 信号通过使每个端口充当多个有序端口来支持无序事务。 所有具有...
the Advanced Microcontroller Bus Architecture (AMBA®) specification’s Advanced eXtensible Interface (AXI) and provides a low-speed, two-wire, serial bus interface to a large number of popular devices. AXI IIC supports all features, except high speed mode, of the Philips I2C-Bus Specification....
AXI Data Width Converter——连接一个主从内存映射进行数据宽度转换 AXI Clock Converter——连接不同时钟域的主从内存映射 AXI Protocol Converter AXI Data FIFO AXI Register Slice AXI MMU 对应不同的主从设备的个数,其中有各种互联方式,不过这些都不需要我们仔细了解,所以说局怎用的时候开发人员再说啦。
Functions of the design are validated in high performance interfaces of embedded system in FPGA. The application shows that the design provided in this paper provides an accurate timing that meets the AXI 4 bus protocol. Data transports between AXI 4 bus devices correctly in the speed of 1.09 ...
The AXI protocol is burst-based.A burst must not cross a 4KB address boundary.在 AXI 传输事务(Transaction)中,数据以突发传输(Burst)的形式组织。一次突发传输中可以包含一至多个数据(Transfer)。每个 transfer 因为使用一个周期,又被称为一拍数据(Beat)。
