Scaling FFT within the wrapper

I am implementing the FFT megacore using a MM-ST SGDMA --->FFT ---> ST-MM SGDMA setup. Therefore, I have a wrapper to accommodate the FFT and slot it into the avalon interface in SOPC. It seems to be working so far, but scaling has yet to be applied. 

 

Is it possible to carry out the scaling automatically within this wrapper?, for instance, as described in the FFT megacore documentation, with a case statement of the exponent value. I'm using Verilog.

i don't see any problem with integrating scaling into your wrapper.
