Field Documentation

energy

q31_t ref_lms_norm_instance_q31::energy

saves previous frame energy.

mu

q31_t ref_lms_norm_instance_q31::mu

step size that controls filter coefficient updates.

numTaps

uint16_t ref_lms_norm_instance_q31::numTaps

number of coefficients in the filter.

pCoeffs

q31_t* ref_lms_norm_instance_q31::pCoeffs

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

postShift

uint8_t ref_lms_norm_instance_q31::postShift

bit shift applied to coefficients.

pState

q31_t* ref_lms_norm_instance_q31::pState

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

recipTable

const q31_t* ref_lms_norm_instance_q31::recipTable

points to the reciprocal initial value table.

x0

q31_t ref_lms_norm_instance_q31::x0

saves previous input sample.
