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, Arlo Reeves
