1.2 Key features

The AMBA Network Interconnect is a highly configurable infrastructure component that

supports:

• 1-128 AXI or AHB-Lite slave interfaces.

• 1-64 master interfaces that can be AXI, AHB-Lite, APB2, or APB3.

• Configuration of:

— an APB port to support 1-16 slaves

— an AXI port to support four region control bits.

• Single-cycle arbitration.

• Full pipelining to prevent master stalls.

• Programmable control for FIFO transaction release.

• Multiple switch networks.

• Complex topologies, including Network On Chip (NOC) loop-back connections between

switches.

• Up to five cascaded switch networks between any master and slave interface pair.

• AXI or AHB-Lite masters and slaves with:

— an address width of 32-64 bits

— a data width of 32, 64, 128, or 256 bits.

• Non-contiguous APB slave address map for a single master interface.

• Independent widths of user-defined sideband signals for each channel.

• Global Programmers View (GPV) for the entire infrastructure that you can configure so

that any master, or a discrete configuration slave interface, can access it. See Chapter 3

Programmers Model.

• Highly flexible timing closure options.
