Member Data Documentation

uint8_t arm_rfft_instance_q31::bitReverseFlagR

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

Definition at line 2293 of file arm_math.h.

uint32_t arm_rfft_instance_q31::fftLenReal

length of the real FFT.

Definition at line 2291 of file arm_math.h.

uint8_t arm_rfft_instance_q31::ifftFlagR

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

Definition at line 2292 of file arm_math.h.

const arm_cfft_instance_q31* arm_rfft_instance_q31::pCfft

points to the complex FFT instance.

Definition at line 2297 of file arm_math.h.

q31_t* arm_rfft_instance_q31::pTwiddleAReal

points to the real twiddle factor table.

Definition at line 2295 of file arm_math.h.

q31_t* arm_rfft_instance_q31::pTwiddleBReal

points to the imag twiddle factor table.

Definition at line 2296 of file arm_math.h.

uint32_t arm_rfft_instance_q31::twidCoefRModifier

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

Definition at line 2294 of file arm_math.h.
