This Figure shows the top-most AXI Interconnect core block diagram. Inside the AXI Interconnect core, a Crossbar core routes traffic between the Slave Interfaces (SI) and Master Interfaces (MI). Along each pathway connecting a SI or MI to the Crossbar, an optional series of AXI Infrastructure cores (couplers) can perform various conversion and buffering functions. The couplers include: Register Slice, Data FIFO, Clock Converter, Data Width Converter and Protocol Converter.

The AXI Interconnect core can be configured to have up to 16 Slave Interfaces (SI) and up to 16 Master Interfaces (MI). Each SI connects to one AXI master device to accept Write and Read transaction requests. Each MI connects to one AXI slave device and issues transactions to slave devices. At the center is the crossbar core that routes traffic on all the AXI channels between the SI and MI. Along each of the pathways between an SI and the crossbar, or between the crossbar and an MI, there can be one or more infrastructure cores that perform various conversion and storage functions.

The crossbar effectively splits the AXI Interconnect core down the middle between the SI-related functional units (SI hemisphere) and the MI-related units (MI hemisphere).
