Power

Overview

Calculates the sum of the squares of the elements in the input vector. The underlying algorithm is used:

   Result = p_src[0] * p_src[0] + p_src[1] * p_src[1] + p_src[2] * p_src[2] + ... + p_src[block_size-1] *
p_src[block_size-1];

There are separate functions for floating point, q31 data types.
