•

Timing isolation:
—

from the external master

—

from the network.

The AMBA Network Interconnect supports the following master interfaces:
•

•

•

The network supports the full AXI protocol using an AXI master interface.

You can configure the following AXI options:

•

Address width of 32-64 bits.

•

Data width of 32, 64, 128, or 256 bits.

•

Data width upsize function that Upsizing data width function on page 2-12 describes.

•

User sideband signal width of 0-32 bits.

•

Data width downsize function that Downsizing data width function on page 2-14 
describes.

•

Frequency domain crossing of type:
—

ASYNC

—

SYNC  1:1

—

SYNC  1:n

—

SYNC  n:1

—

SYNC  n:m.

•

Support for the full AXI protocol.

 

You can reduce the gate count and increase the performance if all attached master that can 
access the master interface does not create any AXI lock transactions.

•

Write issuing capability of 1-32 transactions.

•

Read issuing capability of 1-32 transactions.

•

Buffering that FIFO and clocking function on page 2-15 describes.

•

Timing isolation:
—

from the external slave

—

from the network.
