Reason for having decouple write address, data channels in AXI4

Can someone explain me the advantage of having decouple write address, data channels in AXI4?

In AXI3 with data interleaving we can have multiple masters sending data to various clients but in case of AXI4 we don't support interleaving so how decoupled write address, data channels will help?

Thanks

  • Thanks Yasuhiko, I was trying to understand the reason/advantage of having this decoupled write address, write data channels in AXI4.

    Other than this do we have any other useful case in AXI4?

    By this feature, write data can be issued in advance to its address

    I don't see any advantage in single AXI master case other than above mentioned one. Does multi-master case had some advantage?
