Field Documentation

maxDelay

uint16_t tpt_fir_sparse_q15_s::maxDelay

maximum offset specified by the pTapDelay array.

pCoeffs

q15_t* tpt_fir_sparse_q15_s::pCoeffs

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

pState

q15_t* tpt_fir_sparse_q15_s::pState

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

pTapDelay

int32_t* tpt_fir_sparse_q15_s::pTapDelay

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

stateIndex

uint16_t tpt_fir_sparse_q15_s::stateIndex

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

uTaps

uint16_t tpt_fir_sparse_q15_s::uTaps

number of coefficients in the filter.
