Field Documentation

uint8_t arm_fir_interpolate_instance_f32::L

upsample factor.

const float32_t* arm_fir_interpolate_instance_f32::pCoeffs

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

uint16_t arm_fir_interpolate_instance_f32::phaseLength

length of each polyphase filter component.

float32_t* arm_fir_interpolate_instance_f32::pState

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