Member Data Documentation

◆ bitReverseFlagR

uint8_t arm_rfft_instance_f32::bitReverseFlagR

flag that enables (bitReverseFlagR=1) or disables (bitReverseFlagR=0) bit reversal of output.

Definition at line 2338 of file arm_math.h.

◆ fftLenBy2

uint16_t arm_rfft_instance_f32::fftLenBy2

length of the complex FFT.

Definition at line 2336 of file arm_math.h.

◆ fftLenReal

uint32_t arm_rfft_instance_f32::fftLenReal

length of the real FFT.

Definition at line 2335 of file arm_math.h.

◆ ifftFlagR

uint8_t arm_rfft_instance_f32::ifftFlagR

flag that selects forward (ifftFlagR=0) or inverse (ifftFlagR=1) transform.

Definition at line 2337 of file arm_math.h.

◆ pCfft

arm_cfft_radix4_instance_f32* arm_rfft_instance_f32::pCfft

points to the complex FFT instance.

Definition at line 2342 of file arm_math.h.

◆ pTwiddleAReal

const float32_t* arm_rfft_instance_f32::pTwiddleAReal

points to the real twiddle factor table.

Definition at line 2340 of file arm_math.h.

◆ pTwiddleBReal

const float32_t* arm_rfft_instance_f32::pTwiddleBReal

points to the imag twiddle factor table.

Definition at line 2341 of file arm_math.h.

◆ twidCoefRModifier

uint32_t arm_rfft_instance_f32::twidCoefRModifier

twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table.
