@brief Instance structure for the Q31 normalized LMS filter.

Fields

numTaps: u16

< number of coefficients in the filter.

pState: *mut q31_t

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

pCoeffs: *mut q31_t

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

mu: q31_t

< step size that controls filter coefficient updates.

postShift: u8

< bit shift applied to coefficients.

recipTable: *const q31_t

< points to the reciprocal initial value table.

energy: q31_t

< saves previous frame energy.

x0: q31_t

< saves previous input sample.
