* Improve debug output slightly.
unknown [Tue, 1 Apr 2008 10:37:34 +0000 (12:37 +0200)]
* Change loops back to do while, MontiumCC can't handle while loops.
unknown [Tue, 1 Apr 2008 10:28:47 +0000 (12:28 +0200)]
* Add a missing ! in write_output_regular().
* Use while loops instead of do while, since loop_next checks for zero before
decrementing, not after.
Regular FFT seems to work now, though there seem to be quite some rounding errors.
Testing a larger FFT is hard, since decoding the results is still manual.

* Add a few constraints on the FFT size parameters and make the parameters
abide by those constraints (we're now doing 4 16-point FFT's).
unknown [Thu, 27 Mar 2008 16:41:25 +0000 (17:41 +0100)]
* Use two periods of the sine for testing instead of one and scale the values
to prevent overflow.
unknown [Thu, 27 Mar 2008 16:38:31 +0000 (17:38 +0100)]
* Keep track of the current stage number (not montiumcc compatible) so we
know which twiddle factors we need. This needs checking and improving.
unknown [Thu, 27 Mar 2008 15:45:56 +0000 (16:45 +0100)]
* Actually make the output addressing different in the second half, it was
still the same as the first half.
* Actually do half a stage in do_half_regular_stage() instead of a full
stage.
* Let run do n_t stages instead of just two.
* Call init_libmontiumc() in our main(), so libmontiumc actually works.
unknown [Thu, 27 Mar 2008 15:45:13 +0000 (16:45 +0100)]
* Cleanup and comments.
unknown [Thu, 27 Mar 2008 12:43:19 +0000 (13:43 +0100)]
* Cleanup main.cpp a bit.
* Let the libmontiumc implementation allocate its memories itself, because the
montiumcc version doesn't use global variables for that anymore.
unknown [Thu, 27 Mar 2008 12:42:04 +0000 (13:42 +0100)]
* Prefix all algorithm parameters with PARAM_ so we can still use variable
names such as 'n'.
unknown [Thu, 27 Mar 2008 12:28:15 +0000 (13:28 +0100)]
* Remove some unused code.
* Add more comments.
* Slightly change the behaviour of do_half_regular_stage(), it now intializes
the output addresses once instead of on every cycle. It also waits for the
last write cycle to complete before returning.
unknown [Thu, 27 Mar 2008 11:40:54 +0000 (12:40 +0100)]
* Add current progress of the project. The code compiles and should be able to execute two stages of regular FFT by now.
