3.1.3.4. AXI Translator

AMBA* 4 AXI allows omitting signals from interfaces. The translator bridges between these “incomplete” AMBA* 4 AXI interfaces and the “complete” AMBA* 4 AXI interface on the network interfaces.
Attention: If an Avalon® or AMBA* 4 AXI slave is connected to a master without response ports, the interconnect could ignore transaction responses such as SLAVEERROR or DECODEERROR. This situation could lead to returning invalid data to the master.

The AXI translator is inserted for both AMBA* 4 AXI masters and slaves and performs the following functions:

  • Matches ID widths between the master and slave in 1x1 systems.
  • Drives default values as defined in the AMBA* Protocol Specifications for missing signals.
  • Performs lock transaction bit conversion when an AMBA* 3 AXI master connects to an AMBA* 4 AXI slave in 1x1 systems.
