+/**

+ * @brief Root Mean Square 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 rms value returned here

+ * @return none.

+ *

+ * @details

+ * <b>Scaling and Overflow Behavior:</b>

+ *

+ *\par

+ * The function is implemented using an internal 64-bit accumulator.

+ * The input is represented in 1.31 format, and intermediate multiplication

+ * yields a 2.62 format.

+ * The accumulator maintains full precision of the intermediate multiplication results,

+ * but provides only a single guard bit.

+ * There is no saturation on intermediate additions.

+ * If the accumulator overflows, it wraps around and distorts the result.

+ * In order to avoid overflows completely, the input signal must be scaled down by

+ * log2(blockSize) bits, as a total of blockSize additions are performed internally.

+ * Finally, the 2.62 accumulator is right shifted by 31 bits to yield a 1.31 format value.

+ *
