Detailed Description

Instance structure for the Q15 sparse FIR filter.

Field Documentation

maxDelay

uint16_t ref_fir_sparse_instance_q15::maxDelay

maximum offset specified by the pTapDelay array.

numTaps

uint16_t ref_fir_sparse_instance_q15::numTaps

number of coefficients in the filter.

pCoeffs

const q15_t* ref_fir_sparse_instance_q15::pCoeffs

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

pState

q15_t* ref_fir_sparse_instance_q15::pState

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

pTapDelay

int32_t* ref_fir_sparse_instance_q15::pTapDelay

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

stateIndex

uint16_t ref_fir_sparse_instance_q15::stateIndex

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