## Field Documentation

uint16_t arm_fir_sparse_instance_q7::numTaps

number of coefficients in the filter.

Definition at line 4363 of file arm_math.h.

uint16_t arm_fir_sparse_instance_q7::stateIndex

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

Definition at line 4364 of file arm_math.h.

q7_t* arm_fir_sparse_instance_q7::pState

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

Definition at line 4365 of file arm_math.h.

q7_t* arm_fir_sparse_instance_q7::pCoeffs

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

Definition at line 4366 of file arm_math.h.

uint16_t arm_fir_sparse_instance_q7::maxDelay

maximum offset specified by the pTapDelay array.

Definition at line 4367 of file arm_math.h.

int32_t* arm_fir_sparse_instance_q7::pTapDelay

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

Definition at line 4368 of file arm_math.h.
