5.15.1. ACE-Lite Transaction Support and Limitations

Platform Designer's ACE-Lite interface comprises all the signals specified in the AMBA 4 AXI specification. However, there are limitations on the extent of transactional support that Platform Designer interconnect provides for ACE-Lite transactions. Platform Designer interconnect supports narrow to Wide, Wide to narrow and same Data width, ID width, and Address width adaptation for point-to-point connection (1-manager, 1- subordinate).

Table 101.  Supported ACE-Lite Transactions
Transaction Type Supported Transactions
Non-snoop transactions WriteNoSnoop, ReadNoSnoop
Coherent transactions WriteUnique, ReadOnce
Table 102.  Unsupported ACE-Lite Transactions
Transaction Type Unsupported Transactions
Barrier transactions ReadBarrier, WriteBarrier
Cache Maintenance transactions CleanShared, CleanInvalid, MakeInvalid
Coherent transactions WriteLineUnique

Even though direct ACE-Lite to AXI4 connection is not supported, you can use the Cache Coherency Translator IP to perform the connection between an AXI4 manager to an ACE-Lite subordinate. Refer to Cache Coherency Translator IP in Embedded Peripherals IP User Guide for more details.

Note: Unsupported ACE-Lite transaction interconnect behavior is non-deterministic. Use of unsupported transactions can cause system failure or data corruption.
