- * @param[in,out]  *S points to an instance of the Q15 FIR filter structure.
- * @param[in] 	   numTaps  Number of filter coefficients in the filter. Must be even and greater than or equal to 4.
- * @param[in]      *pCoeffs points to the filter coefficients buffer.
- * @param[in]      *pState points to the state buffer.
- * @param[in]      blockSize is number of samples processed per call.
- * @return The function returns ARM_MATH_SUCCESS if initialization is successful or ARM_MATH_ARGUMENT_ERROR if
- * <code>numTaps</code> is not greater than or equal to 4 and even.
- *
- * <b>Description:</b>
- * \par
- * <code>pCoeffs</code> points to the array of filter coefficients stored in time reversed order:
- * <pre>
- *    {b[numTaps-1], b[numTaps-2], b[N-2], ..., b[1], b[0]}
- * </pre>
- * Note that <code>numTaps</code> must be even and greater than or equal to 4.
- * To implement an odd length filter simply increase <code>numTaps</code> by 1 and set the last coefficient to zero.
- * For example, to implement a filter with <code>numTaps=3</code> and coefficients
- * <pre>
- *     {0.3, -0.8, 0.3}
- * </pre>
- * set <code>numTaps=4</code> and use the coefficients:
- * <pre>
- *     {0.3, -0.8, 0.3, 0}.
- * </pre>
- * Similarly, to implement a two point filter
- * <pre>
- *     {0.3, -0.3}
- * </pre>
- * set <code>numTaps=4</code> and use the coefficients:
- * <pre>
- *     {0.3, -0.3, 0, 0}.
- * </pre>
- * \par
- * <code>pState</code> points to the array of state variables.
- * <code>pState</code> is of length <code>numTaps+blockSize</code>, when running on Cortex-M4 and Cortex-M3  and is of length <code>numTaps+blockSize-1</code>, when running on Cortex-M0 where <code>blockSize</code> is the number of input samples processed by each call to <code>arm_fir_q15()</code>.
