<p>Adds a constant offset to each element of a vector.</p>
<pre>
pDst[n] = pSrc[n] + offset, 0 &lt;= n &lt; blockSize.
</pre><p>The functions support in-place computation allowing the source and destination pointers to reference the same memory buffer. There are separate functions for floating-point, Q7, Q15, and Q31 data types. </p>
