Definition at line 4710 of file arm_math.h.
| uint16_t arm_fir_sparse_instance_q31::maxDelay |
maximum offset specified by the pTapDelay array.
Definition at line 4716 of file arm_math.h.
| uint16_t arm_fir_sparse_instance_q31::numTaps |
number of coefficients in the filter.
Definition at line 4712 of file arm_math.h.
| q31_t* arm_fir_sparse_instance_q31::pCoeffs |
points to the coefficient array. The array is of length numTaps.
