Detailed Description

Instance structure for the Q31 FIR interpolator.

Field Documentation

L

uint8_t ref_fir_interpolate_instance_q31::L

upsample factor.

pCoeffs

const q31_t* ref_fir_interpolate_instance_q31::pCoeffs

points to the coefficient array. The array is of length L*phaseLength.

phaseLength

uint16_t ref_fir_interpolate_instance_q31::phaseLength

length of each polyphase filter component.

pState

q31_t* ref_fir_interpolate_instance_q31::pState

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