| uint16_t arm_fir_sparse_instance_q7::maxDelay |
maximum offset specified by the pTapDelay array.
Definition at line 4744 of file arm_math.h.
| uint16_t arm_fir_sparse_instance_q7::numTaps |
number of coefficients in the filter.
Definition at line 4740 of file arm_math.h.
| q7_t* arm_fir_sparse_instance_q7::pCoeffs |
points to the coefficient array. The array is of length numTaps.
