About the AMBA Network Interconnect
The AMBA Network Interconnect is a highly configurable component that enables you to create
a complete high performance, optimized AMBA-compliant network infrastructure. The
possible configurations for the AMBA Network Interconnect can range from a single bridge
component, for example an AHB to AXI protocol bridge, to a complex infrastructure that
consists of up to 128 masters and 64 slaves of a combination of different AMBA protocols.

An AMBA Network Interconnect configuration can consist of multiple switches with many
topology options. Figure 1-1 shows a top-level block diagram of the AMBA Network
