Member Data Documentation

uint8_t arm_cfft_radix4_instance_q31::bitReverseFlag

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

Definition at line 2130 of file arm_math.h.

uint16_t arm_cfft_radix4_instance_q31::bitRevFactor

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

Definition at line 2134 of file arm_math.h.

uint16_t arm_cfft_radix4_instance_q31::fftLen

length of the FFT.

Definition at line 2128 of file arm_math.h.

uint8_t arm_cfft_radix4_instance_q31::ifftFlag

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

Definition at line 2129 of file arm_math.h.

uint16_t* arm_cfft_radix4_instance_q31::pBitRevTable

points to the bit reversal table.

Definition at line 2132 of file arm_math.h.

q31_t* arm_cfft_radix4_instance_q31::pTwiddle

points to the twiddle factor table.

Definition at line 2131 of file arm_math.h.

uint16_t arm_cfft_radix4_instance_q31::twidCoefModifier

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

Definition at line 2133 of file arm_math.h.
