Data Fields | |
| uint16_t | numTaps |
| q31_t * | pState |
| q31_t * | pCoeffs |
| q31_t | mu |
| uint32_t | postShift |
| q31_t arm_lms_instance_q31::mu |

Referenced by arm_lms_init_q31(), and arm_lms_q31().
| uint16_t arm_lms_instance_q31::numTaps |
number of coefficients in the filter.
Referenced by arm_lms_init_q31(), and arm_lms_q31().
| q31_t* arm_lms_instance_q31::pCoeffs |
points to the coefficient array. The array is of length numTaps.

| uint32_t arm_lms_instance_q31::postShift |
bit shift applied to coefficients.
Referenced by arm_lms_init_q31(), and arm_lms_q31().
| q31_t* arm_lms_instance_q31::pState |
