- * @brief Sum of the squares of the elements of a Q31 vector.
- * @param[in]       *pSrc points to the input vector
- * @param[in]       blockSize length of the input vector
- * @param[out]      *pResult sum of the squares value returned here
- * @return none.
- *
- * @details
- * <b>Scaling and Overflow Behavior:</b>
- *
- * \par
- * The function is implemented using a 64-bit internal accumulator.
- * The input is represented in 1.31 format.
- * Intermediate multiplication yields a 2.62 format, and this
- * result is truncated to 2.48 format by discarding the lower 14 bits.
- * The 2.48 result is then added without saturation to a 64-bit accumulator in 16.48 format.
- * With 15 guard bits in the accumulator, there is no risk of overflow, and the
- * full precision of the intermediate multiplication is preserved.
- * Finally, the return result is in 16.48 format.
