Jared Boone 05eb694c0a Introduce simd32_t type. 
Discontinue use of disagreeable __SIMD #define.
 2017-01-06 16:57:36 -08:00
Jared Boone a1b9f4aa1b Simplify, generalize, share int16_t taps copy function. 
Also prevents compiler loop unrolling in non-critical code, for code size improvement.

Jared Boone 100761481e Fix inaccurate comment. 2015-11-06 09:40:05 -08:00
Jared Boone 86b068be62 Early calculation to reduce pressure on registers. 2015-11-06 09:40:04 -08:00
Jared Boone 424c0eac3f FIRAndDecimateBy2Complex: expose decimation_factor, bring work function into class. 2015-11-06 09:40:04 -08:00
Jared Boone cde15e4271 Generalize fir_and_decimate_by_2_complex_fast. 
Permit decimation_factors other than 2.
Permit tap counts != 64 (but still must be multiple of 8).
Half the amount of tap memory required.
Performance is significantly degraded due to greater flexibility -- most likely due to separate sample buffer shift phase, instead of performing shift during output sample calculation.
