+Subject:     FFT for RISC 2.0
+To:          macgifts@sumex-aim.stanford.edu
+Enclosure:   FFTs-for-RISC-2.sit
+
+Enclosed is a stuffit archive of version 2.0 of my 'C' source code fft library.
+
+   Very-Fast Fourier Transform routines.  Routines are provided for real and complex
+forward and inverse 1d and 2d fourier transforms and 3d complex forward and inverse ffts.
+I coded these to optimize execution speed on Risc processors like the PowerPC.
+All fft sizes must still be a power of two.
+Test programs based on the Numerical Recipes in C routines are provided.
+Also included are some simple applications with source code which time the FFTs.
+See the enclosed read me file for more information.
+
+Revision version 2.0:
+		Rewrote code to rely more on compiler optimization (and be less ugly.)
+		Removed restrictions on too small or too large ffts.
+		Provided a library extension that manages memory for cosine and bit
+reversed counter tables.
+		Added 2d and 3d complex and 2d real ffts.
+		Speeded routines for data too large to fit in primary cache.
+		Changed most testing from Matlab to Numerical Recipes based (because its cheaper.)
+		Changed call parameters (watch out.)
+Revision version 1.21:
+       line 126 of rfftTest.c corrected.
+Revisions version 1.2:
+       I now store the Nyquest point of the real transform where the 0 for the DC term's
+imaginary part used to be.  !! WATCH OUT FOR THIS IF YOU USE rfft !!
+       Added the real inverse Fourier transform.
+
+Revisions version 1.1:
+       Re-arranged to put fft routines in a shared library and changed source file name to fftlib.c.
+       Removed some ugly optimizations that are no longer needed for CodeWarrier.
+
+This code is public domain, do anything you want to with it.
