hi all..
just wanna ask, is there a way to calculate amount of data being process between each system like signal combine in mux??
it was like the display sink, only this block shows the amount of data like (4 byte, 10 byte, 1Kb etc). is there any???
thanks

Also, if you need that value as a signal in the Simulink model you can use the Probe Block in the Signal Attributes library and check the Probe width option. That will give you the number of elements in the signal, you can then multiply that by the number of bytes based on the datatype (e.g. 8 for double).

In your Simulink model, click menu Format>Port/Signal Displays, check "Port Data Types" and "Signal Dimensions", you will see the data type and dimension of the signals between subsystems. If a particular signal is double and its dimension is 3 (if it is one, it is not displayed), then the data size (according to you) would be 24 bytes (a double data takes 8 bytes).
Keep in mind though, the signal line in the Simulink model represents a data flow, not a physical signal line.
