## Field Documentation

uint16_t arm_fir_sparse_instance_q15::numTaps

number of coefficients in the filter.

Definition at line 4349 of file arm_math.h.

uint16_t arm_fir_sparse_instance_q15::stateIndex

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

Definition at line 4350 of file arm_math.h.

q15_t* arm_fir_sparse_instance_q15::pState

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

Definition at line 4351 of file arm_math.h.

q15_t* arm_fir_sparse_instance_q15::pCoeffs

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

Definition at line 4352 of file arm_math.h.

uint16_t arm_fir_sparse_instance_q15::maxDelay

maximum offset specified by the pTapDelay array.

Definition at line 4353 of file arm_math.h.

int32_t* arm_fir_sparse_instance_q15::pTapDelay

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