A Network-on-Chip (NoC) system employing an Advanced eXtensible Interface (AXI) protocol is provided. In AXI4 we don't have write data interleaving, so if your master is issuing multiple write transactions using different IDs, there is a strict ordering requirement that all the WDATA transfers for the first issued AW channel transfer must be completed before any of the WDATA transfers for the second issued AW channel transfer. We recently spoke with a 12-year-old student in the UK, who described a similar strategy that he uses, and called it "jumbling it up". For example, if the transmission unit is a byte or word, you might interleave its bits with several other words. 2. 55 and figure 2-33) suggests to me, that the AXI DMA core can only accept channel arbitration on packet boundaries, and not the "true" interleaving produced by the stream-switch configured for arbitration on, say, every 16 data-beats. Reload to refresh your session. Yes to your first question. If the transaction is indicated as "non-modifiable," and both the Read and Write commands use the same ARID/AWID, the order must be preserved.
