Altera first marketed DSPBuilder then Advanced DSPBuilder. They are licensed separately from quartus (I think) and are launched from simulink.
DSPBuilder supports basic blocks such as counters,adders, registers i.e. things you can do by hand or through schematic anyway.
ADSPBuilder suports filters,fft,mixers...etc, a great tool but does not interface with DSPBuilder blocks readily, this is just to make sure not to make your life very easy.

Thank you for the info.
Is it possible to use the FFT megacore with minimum inputs, if so what are the minimum inputs an FFt megacore needs.
