Detailed Description

Calculates the accumulation of the input vector. Sum is defined as the addition of the elements in the vector. The underlying algorithm is used:

Result = (pSrc[0] + pSrc[1] + pSrc[2] + ... + pSrc[blockSize-1]);

There are separate functions for floating-point, Q31, Q15, and Q7 data types.
