2. About the AXI asynchronous bridge

The AXI asynchronous bridge, AsyncAxi, enables two AXI clock domains to communicate. Figure 1 shows AsyncAxi with data being transferred between two AXI clock domains.

The bridge provides buffered synchronization of the AXI channels:


Write address channel.


Write data channel.


Write response channel.


Read address channel.


Read data channel.

The HDL code is supplied as Verilog.

The major features of the bridge are:

  • single independent AXI master and AXI slave interfaces

  • all AXI channels are buffered independently

  • configurable FIFO buffer depth for each AXI channel

  • dynamic synchronous bypass mode.

The PrimeCell Infrastructure AMBA 3 AXI Asynchronous Bridge (BP132) Design Manual provides more information about these features.
