9 Now working on the test bench for the FFT. Currently, the FFT passes
all test bench "tests." However, the test bench does not yet accurately
report on the success of its work. This remains for future work. Lots
of bugs fixed while making this test bench code work.

(I should mention, while all test benches currently pass, that doesn't
mean that the code works ... yet. I just haven't found the bug that
breaks it.)		 dgisselq 3551d 06h /dblclockfft/trunk/sw/fftgen.cpp
8 This completes the initial work on a test bench for the FFT stage. I
chose to test the odd 2048 stage only, but (hopefully) the testbench
will still apply to all other stages as well. At any rate, based upon
some trial runs, it looks like the FFT may be starting to work as well.

More testing is needed, for certain, but to do that I'm going to have
to figure out just what tests are needed, and how exactly to apply those
tests within the test bench construct.		 dgisselq 3551d 14h /dblclockfft/trunk/sw/fftgen.cpp
6 Lots of work accomplished today. Test benches now exist and work for the:
butterfly, multiply, bitreversal, pairwise FFT stage (dblstage), and the
four-wise FFT stage (qtrstage). Work continues on the single (generic)
FFT stage, and (of course) the FFT isn't ready yet. A second commit will
follow this one shortly with the new files added (oops!--I should've added
them this time--my bad.)		 dgisselq 3552d 01h /dblclockfft/trunk/sw/fftgen.cpp
5 The butterfly_tb is now written, and the butterfly succeeds at the test
bench!		 dgisselq 3552d 08h /dblclockfft/trunk/sw/fftgen.cpp
2 Here's an attempt at a first subversion update. dgisselq 3552d 14h /dblclockfft/trunk/sw/fftgen.cpp
