uint16_t arm_iir_lattice_instance_q15::numStages

number of stages in the filter.

q15_t* arm_iir_lattice_instance_q15::pkCoeffs

points to the reflection coefficient array. The array is of length numStages.

q15_t* arm_iir_lattice_instance_q15::pState

points to the state variable array. The array is of length numStages+blockSize.

q15_t* arm_iir_lattice_instance_q15::pvCoeffs

points to the ladder coefficient array. The array is of length numStages+1.
