Detailed Description

Instance structure for the floating-point FIR interpolator.

Field Documentation

L

uint8_t riscv_fir_interpolate_instance_f32::L

upsample factor.

pCoeffs

const float32_t* riscv_fir_interpolate_instance_f32::pCoeffs

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

phaseLength

uint16_t riscv_fir_interpolate_instance_f32::phaseLength

length of each polyphase filter component.

pState

float32_t* riscv_fir_interpolate_instance_f32::pState

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