Detailed Description

Instance structure for the floating-point sparse FIR filter.

Field Documentation

maxDelay

uint16_t ref_fir_sparse_instance_f32::maxDelay

maximum offset specified by the pTapDelay array.

numTaps

uint16_t ref_fir_sparse_instance_f32::numTaps

number of coefficients in the filter.

pCoeffs

const f32_t* ref_fir_sparse_instance_f32::pCoeffs

points to the coefficient array. The array is of length numTaps.

pState

f32_t* ref_fir_sparse_instance_f32::pState

points to the state buffer array. The array is of length maxDelay+blockSize-1.

pTapDelay

int32_t* ref_fir_sparse_instance_f32::pTapDelay

points to the array of delay values. The array is of length numTaps.

stateIndex

uint16_t ref_fir_sparse_instance_f32::stateIndex

state buffer index. Points to the oldest sample in the state buffer.
