Detailed Description

Instance structure for the floating-point FIR interpolator.

Field Documentation

L

uint8_t tpt_fir_interpolate_q31_s::L

upsample factor.

pCoeffs

const q31_t* tpt_fir_interpolate_q31_s::pCoeffs

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

phaseLength

uint32_t tpt_fir_interpolate_q31_s::phaseLength

length of each polyphase filter component.

pState

q31_t* tpt_fir_interpolate_q31_s::pState

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