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. The signals are present for point-to-point (1-manager, 1- subordinate).
Transaction Type | Supported Transactions |
---|---|
Non-snoop transactions | WriteNoSnoop, ReadNoSnoop |
Coherent transactions | WriteUnique, ReadOnce |
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 Intel FPGA IP in Embedded Peripherals IP User Guide for more details.
