## Field Documentation

## ◆ maxDelay

uint16_t arm_fir_sparse_instance_q15::maxDelay

maximum offset specified by the pTapDelay array.

Definition at line 4483 of file arm_math.h.

## ◆ numTaps

uint16_t arm_fir_sparse_instance_q15::numTaps

number of coefficients in the filter.

Definition at line 4479 of file arm_math.h.

## ◆ pCoeffs

const q15_t* arm_fir_sparse_instance_q15::pCoeffs

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

Definition at line 4482 of file arm_math.h.

## ◆ pState

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 4481 of file arm_math.h.

## ◆ pTapDelay

int32_t* arm_fir_sparse_instance_q15::pTapDelay

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

Definition at line 4484 of file arm_math.h.

## ◆ stateIndex

uint16_t arm_fir_sparse_instance_q15::stateIndex

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