Member Data Documentation

◆ energy

q31_t arm_lms_norm_instance_q31::energy

saves previous frame energy.

Definition at line 4424 of file arm_math.h.

◆ mu

q31_t arm_lms_norm_instance_q31::mu

step size that controls filter coefficient updates.

Definition at line 4421 of file arm_math.h.

◆ numTaps

uint16_t arm_lms_norm_instance_q31::numTaps

number of coefficients in the filter.

Definition at line 4418 of file arm_math.h.

◆ pCoeffs

q31_t* arm_lms_norm_instance_q31::pCoeffs

points to the coefficient array. The array is of length numTaps.

Definition at line 4420 of file arm_math.h.

◆ postShift

uint8_t arm_lms_norm_instance_q31::postShift

bit shift applied to coefficients.

Definition at line 4422 of file arm_math.h.

◆ pState

q31_t* arm_lms_norm_instance_q31::pState

points to the state variable array. The array is of length numTaps+blockSize-1.

Definition at line 4419 of file arm_math.h.

◆ recipTable

q31_t* arm_lms_norm_instance_q31::recipTable

points to the reciprocal initial value table.

Definition at line 4423 of file arm_math.h.

◆ x0

q31_t arm_lms_norm_instance_q31::x0

saves previous input sample.
