Notational Conventions

The code and syntax used in this document for function and variable declarations are written in the ANSI C style. However, versions of Intel IPP for different processors or operating systems may, of necessity, vary slightly.

Product and Performance Information

Performance varies by use, configuration and other factors. Learn more at www.Intel.com/PerformanceIndex.

Notice revision #20201201

This document uses the following notational conventions:

Convention

Explanation

Example

THIS TYPE STYLE

Used in the text for the Intel IPP constant identifiers.

IPPI_MAX_64S

This type style

Mixed with the uppercase in structure names; also used in function names, code examples and call statements.

IppLibraryVersion, void ippsFree()

This type style

Parameters in function prototypes and parameters description.

value, srcStep

x(n) and x[n]

Used to represent a discrete 1D signal. The notation x(n) refers to a conceptual signal, while the notation x[n] refers to an actual vector. Both of these are annotated to indicate a specific finite range of values.

x[n], 0 ≤ n< len

Typically, the number of elements in vectors is denoted by len. Vector names contain square brackets as distinct from vector elements with current index n.

The expression pDst[n] = pSrc[n] + val implies that each element pDst[n] of the vector pDst is computed for each n in the range from 0 to len-1. Special cases are regarded and described separately.

Ipp<data-domain> and Ipp prefixes

All structures and enumerators, specific for a particular data-domain have the Ipp<data-domain> prefix, while those common for entire Intel IPP software have the Ipp prefix.

IppsROI, IppLibraryVersion
