Field Documentation

numStages

uint16_t riscv_iir_lattice_instance_q31::numStages

number of stages in the filter.

pkCoeffs

q31_t* riscv_iir_lattice_instance_q31::pkCoeffs

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

pState

q31_t* riscv_iir_lattice_instance_q31::pState

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

pvCoeffs

q31_t* riscv_iir_lattice_instance_q31::pvCoeffs

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