- * @brief Processing function for the Q15 FIR interpolator.
- * @param[in] *S points to an instance of the Q15 FIR interpolator structure.
- * @param[in] *pSrc points to the block of input data.
- * @param[out] *pDst points to the block of output data.
- * @param[in] blockSize number of input samples to process per call.
- * @return none.
- *
- * <b>Scaling and Overflow Behavior:</b>
- * \par
- * The function is implemented using a 64-bit internal accumulator.
- * Both coefficients and state variables are represented in 1.15 format and multiplications yield a 2.30 result.
- * The 2.30 intermediate results are accumulated in a 64-bit accumulator in 34.30 format.
- * There is no risk of internal overflow with this approach and the full precision of intermediate multiplications is preserved.
- * After all additions have been performed, the accumulator is truncated to 34.15 format by discarding low 15 bits.
- * Lastly, the accumulator is saturated to yield a result in 1.15 format.
