424c0eac3f FIRAndDecimateBy2Complex: expose decimation_factor, bring work function into class. 2015-11-06 09:40:04 -08:00

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.
