A_ALIGNED TWIDDLE_FACTORS_PREFIX_TAB dsp16_t | dsp16_twiddle_factors2 [DSP16_N_TWIDDLE_FACTORS] |
This table has been generated using the following algorithm:. | |
Twiddle factors table | |
#define | DSP16_N_TWIDDLE_FACTORS 1024 |
This constant defines the size of the twiddle factors table we want to store in memory. i.e.: if we want to compute a 1024-point (or less) complex FFT, we will define this constant as follow:. | |

TWIDDLE_FACTORS_PREFIX_TAB dsp16_t dsp16_twiddle_factors[] |
This constant permits you to add attributes to the twiddle factors table.
It is useful if you want to store the table into another memory for example.
i.e.:.
#define TWIDDLE_FACTORS_PREFIX_TAB const
This constant permits you to add attributes to the twiddle factors table.
It is useful if you want to store the table into another memory for example.
i.e.:.
for i=0:4:DSP16_N_TWIDDLE_FACTORS, k = i/(DSP16_N_TWIDDLE_FACTORS*4); w = exp(-2*PI*%i*k); end;
