Descriptors

The descriptors element further describes the operation. Descriptors are individual characters that indicate additional details of the operation.

The following descriptors are used in signal processing functions:

Descriptor Description Example

I

Operation is in-place (default is not-in-place).

ippsAdd_16s_I

Sfs

Saturation and fixed scaling mode (default is saturation and no scaling).

ippsConvert_16s8s_Sfs

P

Operation is performed for the specified number of vectors.

ippsIIR_32f _P

If the function has more than one descriptor, they are presented in the function name in alphabetical order.

Many functions have no descriptors listed above. Such functions operate with the default behavior.
