Definition at line 4724 of file arm_math.h.
| uint16_t arm_fir_sparse_instance_q15::maxDelay |
maximum offset specified by the pTapDelay array.
Definition at line 4730 of file arm_math.h.
| uint16_t arm_fir_sparse_instance_q15::numTaps |
number of coefficients in the filter.
Definition at line 4726 of file arm_math.h.
| q15_t* arm_fir_sparse_instance_q15::pCoeffs |
points to the coefficient array. The array is of length numTaps.
