| len | Specifies the number of elements in a buffer. | |
| pDst | Pointer to a destination buffer. | |
| pSrc | Pointer to a source buffer. | |
| scaleFactor | Specifies an integer scaling factor for the Sfs operation. The returned result is multiplied by 2^(-scaleFactor). | |
| vdiv | Specifies the denominator. | |
| vsub | Specifies the subtrahend. |
These functions step through vector elements in a source buffer, subtract vsub from each element, and divide the differences by vdiv.
The results can be written to a destination buffer or written back to the source buffer.
The 16-bit unsigned and 16-bit signed versions perform an integer scaling operation before writing the results.
The normalize operation is performed as follows.
Dst = (Src - vsub) / vdiv
