Member Data Documentation

◆ bitReverseFlag

uint8_t arm_cfft_radix4_instance_f32::bitReverseFlag

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

Definition at line 2185 of file arm_math.h.

◆ bitRevFactor

uint16_t arm_cfft_radix4_instance_f32::bitRevFactor

bit reversal modifier that supports different size FFTs with the same bit reversal table.

Definition at line 2189 of file arm_math.h.

◆ fftLen

uint16_t arm_cfft_radix4_instance_f32::fftLen

length of the FFT.

Definition at line 2183 of file arm_math.h.

◆ ifftFlag

uint8_t arm_cfft_radix4_instance_f32::ifftFlag

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

Definition at line 2184 of file arm_math.h.

◆ onebyfftLen

float32_t arm_cfft_radix4_instance_f32::onebyfftLen

value of 1/fftLen.

Definition at line 2190 of file arm_math.h.

◆ pBitRevTable

uint16_t* arm_cfft_radix4_instance_f32::pBitRevTable

points to the bit reversal table.

Definition at line 2187 of file arm_math.h.

◆ pTwiddle

float32_t* arm_cfft_radix4_instance_f32::pTwiddle

points to the Twiddle factor table.

Definition at line 2186 of file arm_math.h.

◆ twidCoefModifier

uint16_t arm_cfft_radix4_instance_f32::twidCoefModifier

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