b42d3cc9d5 Move BasebandStatsCollector code into .cpp, as much as possible. 
Still have template for callback, but hopefully will mitigate bloat when BasebandStatsCollector is used in multiple places.

Jared Boone
6d3cdb9bbf Separate template/callback code from method code. 
...for more small reductions in code size.

d9017530c6 Moved baseband temporary buffers back into class member variables. 
Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.

5547782f5a Improve FFT twiddle factor precisions using Python SymPy. 
Python math, numpy, scipy produce values with significant rounding errors.
 2016-01-03 21:02:44 -08:00
Jared Boone
963b6e257a FFT twiddles can be used for all K <= table length. 
Change assert to allow FFTs < 8.
 2016-01-03 20:25:31 -08:00
Jared Boone
54e59cc224 Hard-code K=8 FFT twiddle constants for now. 
So low on baseband RAM! This eliminates the sin_f32() function and table, which is only used in the FFT, for the moment.

c179b9e1cd Move FIR filter configs to common/, so M0 can use it. 
Planning to pass from M0 to M4 so M4 doesn't need to keep all these different filter configs in text section.

07cd99d85d Removing baseband MessageHandlerMap. 
It's a bit heavy (362 bytes smaller with switch/case implementation), hard to access to add/remove handlers, doesn't bubble events like I'd like. (I'm going to bubble events to the baseband processor shortly.)
