Member Data Documentation

maxDelay

uint16_t arm_fir_sparse_instance_q15::maxDelay

maximum offset specified by the pTapDelay array.

Definition at line 4610 of file arm_math.h.

numTaps

uint16_t arm_fir_sparse_instance_q15::numTaps

number of coefficients in the filter.

Definition at line 4606 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 4609 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 4608 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 4611 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.
