Primitives Concepts 2
This chapter explains the purpose and structure of the Intel ® Integrated Performance Primitives (Intel ® IPP)
for Intel ® Architecture software and looks over some of the basic concepts used in the image part of Intel IPP.
It also describes the supported data formats and operation modes, and defines function naming conventions
in the document.
Function Naming
Naming conventions for the Intel IPP functions are similar for all covered domains.
Function names in Intel IPP have the following general format:
ipp_][]();
The elements of this format are explained in the sections that follow.
Data-Domain
The data-domain is a single character that denotes the subset of functionality to which a given function
belongs. The current version of Intel IPP supports the following data-domains:
s
i
m
r
g
for signals (expected data type is a 1D signal)
for images and video (expected data type is a 2D image)
for matrices (expected data type is a matrix)
for realistic rendering functionality and 3D data processing (expected data type
depends on supported rendering techniques)
for signals of fixed length
For example, function names that begin with ippi signify that respective functions are used for image or
video processing.
Name
The name field identifies what function does and has the following format:
= [_modifier]
The operation component is one ore more words, acronyms, and abbreviations that describe the core
operation.
The modifier component, if present, is a word or abbreviation that denotes a slight modification or variation
of the given function.
For example, names without modifiers: Add, RGBToYCbCr, MorphAddGetSize; with modifiers:
DCT8x8Inv_2x2, DCT8x8Inv_4x4, RGBToYCbCr_JPEG.
Data Types
The datatype field indicates data types used by the function, in the following format:
