- * @brief Initialization function for the Q7 sparse FIR filter.
- * @param[in,out] *S points to an instance of the Q7 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 samples processed by the <code>arm_fir_sparse_q7()</code> function.
