- * @brief Sum of the squares of the elements of a Q7 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 32-bit internal accumulator.     
- * The input is represented in 1.7 format.   
- * Intermediate multiplication yields a 2.14 format, and this    
- * result is added without saturation to an accumulator in 18.14 format.    
- * With 17 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 18.14 format.
