128, 256, 512, 1024 Points FFT.

If I want to design a module consists of 128, 256, 512 and 1024 points FFT (the users can select the N - points FFT they want), what is the best way to do it? I know, in software such as C and Matlab...

that's a good point, i didn't stop to think about resource usage and parallel loading for example.

cwj: take a look at Altera's Streaming and Variable Streaming FFT architectures to get an idea of how they load data and process in serial. you can create one in the MegaWizard and simulate using the generated test bench which should point you in the right direction.
