Before I sit down to the task of writing my own 2D FFT routine in 68000
assembler, I'd like to know if anyone out there already has the source
for such a routine that they'd be willing to share.

The routine I'm looking for makes all sacrifices for fast execution, i.e.
integer arithmetic and data scaling, to make a (8bit)x512x512 point transform
execute in less than 2 minutes on an 8MHz 68000 or 16MHz 68020/68881.

Even routines falling short of this performance may help me design my own
routine, so I'm

Thankful for any FFT 680x0 sources,
