Dave Flogeras 41a3f92259 Implement arm_rfft_fast_init_f32 with new separate initialize functions. 7 years ago
Dave Flogeras 0f5b33ee1b Split rfft_fast_init_f32 into separate initializer functions. 
The rationale here is that if the caller knows the size FFT they require
at compile time, only the look-up tables required for that size are
placed in the data segment (ROM).  This saves between ~40k to ~80k of
ROM when only using a single FFT size.
