5.14. AMBA* 4 AXI-Lite Protocol Specification Support (version 2.0)

AMBA* 4 AXI-Lite is a sub-set of AMBA* 4 AXI. It is suitable for simpler control register-style interfaces that do not require the full functionality of AMBA* 4 AXI. 19

Platform Designer supports the following AMBA* 4 AXI-Lite features:

  • Transactions with a burst length of 1.
  • Data accesses use the full width of a data bus (32- bit or 64-bit) for data accesses, and no narrow-size transactions.
  • Non-modifiable and non-bufferable accesses.
  • No exclusive accesses.
19 This document refers to the new AXI "manager" and AXI "subordinate" inclusive terms to replace outmoded terms, as the latest version of the AMBA® AXI and ACE Protocol Specification describes.
