It’s demanding. . The solution requires two queues (of the same type) and a search-and-compare method. The second and third criterion are inherent to the AXI protocol: For (2), the valid signal has to be held high until the ready signal goes high. The interleaving system should therefore limit neither the number of transactions that can be outstanding to channels nor the controller’s ability to schedule the transactions that it has received. This feature is actually exists in the IP AXI-Crossbar which is part of the AXI-Interconnect hierarchy.

To extend the read interleave question & assuming this use case only valid in AXI interconnect. 5 Write data interleaving] "The order in which a slave receives the first data item of each transaction must be the same as the order in which it receives the addresses for the transactions There is no write data interleaving in AXI4. For example, if the transmission unit is a byte or word, you might interleave its bits with several other words. You switched accounts on another tab or window. Course interleaving is enabled with the memory controller mapping to multiple address regions. The various AXI channels operate mostly independently of each other, so there is no requirement that a master wait for the B channel response to one write transaction before starting a new AW or W channel transfer. In this work, single master and single slave communication using AXI protocol with 32-bit SARM are designed. Re-ordering implies the transactions complete in a different order to that the AR channel transfers were completed, whereas interleaving suggests that more that one read data stream can be active, so data in successive transfers could be for different transactions. [13] What are the difference between AXI3 and AXI4 and which. It is not limited to AXI busses it is a general term which affects the bus transfers and leaves undesirable results (performance hits).
