The AXI Interconnect provides the necessary infrastructure to connect as many as 8 shared AXI Slaves to as many as 4 AXI Bus Masters.

AXI defines 5 channels (write address, read address, write data, read data, write response) for its interface signaling between AXI Master and AXI Slave, but does not define a single way that an AXI Master must be connected to an AXI Slave.  In general, an interconnect module is necessary when more than one Master and/or more than one Slave is required.

The AXI Interconnect is responsible for routing a transaction from a given Master to the appropriate Slave (decoding and switching), and ensuring that the various Master transactions do not interfere with each other (arbitration.)
