Field Documentation

uint8_t bitReverseFlag

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

Definition at line 2084 of file arm_math.h.

uint16_t bitRevFactor

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

Definition at line 2088 of file arm_math.h.

uint16_t fftLen

length of the FFT.

Definition at line 2082 of file arm_math.h.

uint8_t ifftFlag

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

Definition at line 2083 of file arm_math.h.

float32_t onebyfftLen

value of 1/fftLen.

Definition at line 2089 of file arm_math.h.

uint16_t* pBitRevTable

points to the bit reversal table.

Definition at line 2086 of file arm_math.h.

float32_t* pTwiddle

points to the Twiddle factor table.

Definition at line 2085 of file arm_math.h.
