About the GIC-600AE
•
In systems where there is an available free-flowing transport layer in place, existing buses can
be used to route the GIC traffic.
•
The GIC-600AE includes a narrow, 16-bit, AXI4-Stream interconnect that can be used for
routing internal traffic.
The following figure shows a GIC-600AE with a free-flowing interconnect in an example system.

A free-flowing channel is clear to transmit a transaction that arrives at its
destination without any non-transient dependencies on other transactions.
The following figure shows a GIC-600AE with interconnect in an example system. The cross-chip
interfaces enable communication between cores in a multichip configuration.
