Hi,

If you use the Scaler as is (without controlling it via the run-time control) then the input is fixed per the configuration in the SOPC.

If you use the run-time control then the input resolution is the maximum resolution you can input.

hi, ra2m, thanks for reply.

do you mean if I use the run-time control of scaler which means I can input other resolution equal to or less than the maximum resolution I set in sopc?

But it seems that there is no register of scaler for me to explictly change the scaler to adapt to the input resolution at run time.
