Abstract
An advanced extensible interface (AXI) bus is disclosed. 2×2 AXI crossbars are used as basic units; each including two slave interfaces and two master interfaces; an N2 full Mesh fabric is built by using the basic units, so that each slave interface on one basic unit is connected to a master interface on another basic unit to form a first path. A data transmission method includes: receiving, through a master interface of a basic unit, a data packet sent by a master device; sending, through a slave interface of the basic unit, the data packet to a destination slave device by using an AXI bus; receiving, through the slave interface of the basic unit, a response packet returned by the destination slave device, where the basic units are 2×2 AXI crossbars and the AXI bus is based on an N2 full mesh fabric built by using the basic units.
