5.1.4.2. 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.
Figure 155. AXI Slave Network InterfaceAn AMBA* 4 AXI slave supports up to 256 beat INCR bursts, QoS signals, and data sideband signals.

The AXI translator is inserted for both AMBA* 4 AXI master and slave, and performs the following functions:

  • Matches ID widths between 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.
