Avalon ST Multiplexer -> is it possible to concatenate?

Hi,

As for the Avalon ST Multiplexer (Embedded Peripheral) -> is it possible to concatenate such several multiplexers?

The Avalon ST Multiplexer iself has 16 input interfaces, but I need to multiplex 20. How is it possible?

Thanks!

    No reason why not. Just connect them together in Platform Designer.

  • Let's say I concatenate them in the following way:

    So, how will the inputs in0 through in19 be scheduled on the OUT output?

    The in0 .. in19 are packet based 16bits width inputs (with start-of-frame and end-of-frame signals).

    How should I configure the MUX0 and MUX1 so that on the OUT port will be observed packets in0, in1, ... in19 in this certain order (in0, in1, ..., in19)?

    Thanks!

  • The Avalon-ST Multiplexer doesn't have the Packet User Signal, only Start of Packet and End Of Packet.

    Again, as for the picture below,

    how will the inputs in0 through in19 be scheduled on the OUT output?

    The in0 .. in19 are packet based 16bits width inputs (with start-of-frame and end-of-frame signals).

    How should I configure the MUX0 and MUX1 so that on the OUT port will be observed packets in0, in1, ... in19 in this certain order (in0, in1, ..., in19)?

    Thanks!

    I would think you should have cascading muxes so a total of 3: in0-in15 on one, in16-in19 on the second one and the outputs of those two selectable through a third one.
