- * @param[in,out] *S points to an instance of the floating-point FIR filter structure.
- * @param[in] numTaps Number of filter coefficients in the filter.
- * @param[in] *pCoeffs points to the filter coefficients buffer.

- * <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>
- * \par
- * <code>pState</code> points to the array of state variables.
- * <code>pState</code> is of length <code>numTaps+blockSize-1</code> samples, where <code>blockSize</code> is the number of input samples processed by each call to <code>arm_fir_f32()</code>.
