Definition at line 4490 of file arm_math.h.

## Field Documentation

## ◆ maxDelay

uint16_t arm_fir_sparse_instance_q7::maxDelay

maximum offset specified by the pTapDelay array.

Definition at line 4496 of file arm_math.h.

## ◆ numTaps

uint16_t arm_fir_sparse_instance_q7::numTaps

number of coefficients in the filter.

Definition at line 4492 of file arm_math.h.

## ◆ pCoeffs

const q7_t* arm_fir_sparse_instance_q7::pCoeffs

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

Definition at line 4495 of file arm_math.h.

## ◆ pState

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 4494 of file arm_math.h.

## ◆ pTapDelay

int32_t* arm_fir_sparse_instance_q7::pTapDelay

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

Definition at line 4497 of file arm_math.h.

## ◆ stateIndex

uint16_t arm_fir_sparse_instance_q7::stateIndex

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