2.1 About the functions

You can consider the AMBA Network Interconnect to be built from functions that each have

their own transfer function. A transfer function can:

• a domain crossing, for example:

— clock domain crossing

— data width crossing.

• used to create timing isolation, for optimizing critical network paths for latency.

Within a domain, a switch, or multiple switches, can exist to enable routing paths between any

slave interface to any master interface.

The functions are configured into routing switches or Interface Blocks (IBs) and you can use

AMBA Designer to create highly complex topologies using these modules. For more

information, see the AMBA Designer (ADR-301) User Guide and AMBA Network Interconnect

(NIC-301) Supplement to AMBA Designer (ADR-301) User Guide.
