Member Data Documentation

◆ bitReverseFlag

uint8_t arm_cfft_radix4_instance_q15::bitReverseFlag

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

Definition at line 2104 of file arm_math.h.

◆ bitRevFactor

uint16_t arm_cfft_radix4_instance_q15::bitRevFactor

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

Definition at line 2108 of file arm_math.h.

◆ fftLen

uint16_t arm_cfft_radix4_instance_q15::fftLen

length of the FFT.

Definition at line 2102 of file arm_math.h.

◆ ifftFlag

uint8_t arm_cfft_radix4_instance_q15::ifftFlag

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

Definition at line 2103 of file arm_math.h.

◆ pBitRevTable

const uint16_t* arm_cfft_radix4_instance_q15::pBitRevTable

points to the bit reversal table.

Definition at line 2106 of file arm_math.h.

◆ pTwiddle

const q15_t* arm_cfft_radix4_instance_q15::pTwiddle

points to the twiddle factor table.

Definition at line 2105 of file arm_math.h.

◆ twidCoefModifier

uint16_t arm_cfft_radix4_instance_q15::twidCoefModifier

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

Definition at line 2107 of file arm_math.h.
