Member Data Documentation

◆ energy

q15_t arm_lms_norm_instance_q15::energy

saves previous frame energy.

Definition at line 4379 of file arm_math.h.

◆ mu

q15_t arm_lms_norm_instance_q15::mu

step size that controls filter coefficient updates.

Definition at line 4376 of file arm_math.h.

◆ numTaps

uint16_t arm_lms_norm_instance_q15::numTaps

Number of coefficients in the filter.

Definition at line 4373 of file arm_math.h.

◆ pCoeffs

q15_t* arm_lms_norm_instance_q15::pCoeffs

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

Definition at line 4375 of file arm_math.h.

◆ postShift

uint8_t arm_lms_norm_instance_q15::postShift

bit shift applied to coefficients.

Definition at line 4377 of file arm_math.h.

◆ pState

q15_t* arm_lms_norm_instance_q15::pState

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

Definition at line 4374 of file arm_math.h.

◆ recipTable

const q15_t* arm_lms_norm_instance_q15::recipTable

Points to the reciprocal initial value table.

Definition at line 4378 of file arm_math.h.

◆ x0

q15_t arm_lms_norm_instance_q15::x0

saves previous input sample.
