#include <arm_math.h>
Data Fields | |
| uint32_t | fftLenReal |
| length of the real FFT. | |
| uint8_t | ifftFlagR |
| flag that selects forward (ifftFlagR=0) or inverse (ifftFlagR=1) transform. | |
| uint8_t | bitReverseFlagR |
| flag that enables (bitReverseFlagR=1) or disables (bitReverseFlagR=0) bit reversal of output. | |
| uint32_t | twidCoefRModifier |
| twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table. | |
| q15_t * | pTwiddleAReal |
| points to the real twiddle factor table. | |
| q15_t * | pTwiddleBReal |
| points to the imag twiddle factor table. | |
| const arm_cfft_instance_q15 * | pCfft |
| points to the complex FFT instance. | |
