Member Data Documentation

uint8_t arm_rfft_instance_f32::bitReverseFlagR

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

Definition at line 2320 of file arm_math.h.

uint16_t arm_rfft_instance_f32::fftLenBy2

length of the complex FFT.

Definition at line 2318 of file arm_math.h.

uint32_t arm_rfft_instance_f32::fftLenReal

length of the real FFT.

Definition at line 2317 of file arm_math.h.

uint8_t arm_rfft_instance_f32::ifftFlagR

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

Definition at line 2319 of file arm_math.h.

arm_cfft_radix4_instance_f32* arm_rfft_instance_f32::pCfft

points to the complex FFT instance.

Definition at line 2324 of file arm_math.h.

float32_t* arm_rfft_instance_f32::pTwiddleAReal

points to the real twiddle factor table.

Definition at line 2322 of file arm_math.h.
