axi ordering

tom

Hi 
 the master is connected  to axi-interconnect and  two slaves(A and B) are connected to axi-interconnect.
The master send a write transcation(AA)   to  slave A and then send  a write transcation(BB)   to slave B with same ID.
the two transcations with the same ID, axi mention that  the master should receive A1's response  and then B1's response from axi-interconnect..

Now,i have some question about that.
the two transcations must arrive to slave A and then arrive to slave B?
is it possible that  the transcations can arrive to two slaves  out of order and  axi-interconnect. send their response to master in order ?

thanks

    I'm not sure where in the AXI protocol you see "detailed descriptions" of how to implement topologies with more masters and slaves as the AXI protocol is written to describe point-to-point master-slave connections.

    The only area I can think you might be referring to us the section on "Transaction ordering", which talks about how masters and slaves handle transactions with different IDs, and how interconnects append bits to the master issued IDs. If this is what you were describing, it isn't much detail on how to implement the interconnects, it is only explaining why the IDs the slave sees might not be the same ones the masters issue.
