Member Data Documentation

q15_t arm_lms_norm_instance_q15::energy

saves previous frame energy.

q15_t arm_lms_norm_instance_q15::mu

step size that controls filter coefficient updates.

uint16_t arm_lms_norm_instance_q15::numTaps

Number of coefficients in the filter.

q15_t* arm_lms_norm_instance_q15::pCoeffs

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

uint8_t arm_lms_norm_instance_q15::postShift

bit shift applied to coefficients.

q15_t* arm_lms_norm_instance_q15::pState

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

q15_t* arm_lms_norm_instance_q15::recipTable

Points to the reciprocal initial value table.

q15_t arm_lms_norm_instance_q15::x0

saves previous input sample.
