-/**
- * @brief  Initialization function for the Q31 sparse FIR filter.
- * @param[in,out] *S         points to an instance of the Q31 sparse FIR structure.
- * @param[in]     numTaps    number of nonzero coefficients in the filter.
- * @param[in]     *pCoeffs   points to the array of filter coefficients.
- * @param[in]     *pState    points to the state buffer.
- * @param[in]     *pTapDelay points to the array of offset times.
- * @param[in]     maxDelay   maximum offset time supported.
- * @param[in]     blockSize  number of samples that will be processed per block.
- * @return none
- *
- * <b>Description:</b>
- * \par
- * <code>pCoeffs</code> holds the filter coefficients and has length <code>numTaps</code>.
- * <code>pState</code> holds the filter's state variables and must be of length
- * <code>maxDelay + blockSize</code>, where <code>maxDelay</code>
- * is the maximum number of delay line values.
- * <code>blockSize</code> is the number of words processed by <code>arm_fir_sparse_q31()</code> function.
