Zusammenfassung:An interconnect for providing data access between nodes of an integrated circuit, comprises a predetermined type of ingress port comprising routing circuitry responsive to a read-triggering request received from a requesting node to select from a selected egress port via which signals are to be routed to a destination node to control the destination node to return at least one read response dependent on data read from a target storage location. In response to the read-triggering request, the routing circuitry obtains a relative data width indication specifying whether read responses received at the selected egress port have a narrower data width than read responses to be provided to the requesting node by the predetermined type of ingress port, and controls allocation of resource for handling the read-triggering request or the at least one read response depending on the relative data width indication.
