Definition at line 2152 of file arm_math.h.
| uint8_t arm_cfft_radix4_instance_q31::bitReverseFlag |
flag that enables (bitReverseFlag=1) or disables (bitReverseFlag=0) bit reversal of output.
Definition at line 2156 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 2160 of file arm_math.h.
| uint16_t arm_cfft_radix4_instance_q31::fftLen |
length of the FFT.
Definition at line 2154 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 2155 of file arm_math.h.
| const uint16_t* arm_cfft_radix4_instance_q31::pBitRevTable |
points to the bit reversal table.
