Parameter structure for IQ31 real FFT functions.
bool msp_fft_iq31_params::bitReverse |
Perform bit-reversal of the input before transformation. This step is mandatory, this parameter only exists for applications that might handle bit reversal when storing the data samples to memory. If not this needs to be set to true.
uint16_t msp_fft_iq31_params::length |
Length of the source data, must be a power of two.
const _q15* msp_fft_iq31_params::twiddleTable |
Pointer to the twiddle coefficient table with size greater than or equal to the source length. When using LEA this can be a NULL pointer.
