1 Intel® Integrated Performance Primitives Reference Manual, Volume 1: Signal Processing
Volume Overview
1
This manual describes the structure, operation and functions of the Intel® Integrated Performance Primitives
(Intel® IPP) for Intel® architecture that operate on one-dimensional signals. The manual explains the
concepts of Intel IPP, as well as specific data type definitions and operation models used in the signal
processing domain, and provides detailed descriptions of the Intel IPP signal processing functions. The
functions are combined in groups by their functionality. Each group of functions is described in a separate
chapter (chapters 3 through 14).
For more information about signal processing concepts and algorithms, refer to the books and papers listed
in the Bibliography.
What's New
This Reference Manual documents Intel® Integrated Performance Primitives (Intel® IPP) 8.1 release.
Notational Conventions
The code and syntax used in this manual 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.
This manual uses the following notational conventions:
Explanation
Used in the text for the Intel IPP
constant identifiers.
Mixed with the uppercase in
structure names; also used in
function names, code examples
and call statements.
Example
IPPI_MAX_64S
IppLibraryVersion,
void ippsFree()
Parameters in function prototypes
and parameters description.
value, srcStep
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.

Intel® Integrated Performance
Primitives Concepts
2
This chapter explains the structure of the Intel® Integrated Performance Primitives (Intel® IPP) software and
some of the basic concepts used in the signal processing part of Intel IPP. It also defines function naming
conventions in the manual, describes the supported data formats and operation modes.
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_< datatype>[_]()
The elements of this format are explained in the sections that follow.
NOTE
In this manual, each function is introduced by its short name (without the ipps prefix and modifiers)
and a brief description of its purpose.
The ipps prefix in function names is always used in the code examples. In the text, this prefix is
usually omitted when referring to the function group.
Data-Domain
The data-domain element is a single character that denotes the group of functionality to which a given
function belongs. The main distinction among these groups is the type of input data. Intel IPP supports the
following data-domains:
s
i
m
r
realistic rendering functionality and 3D data processing (type of input data type depends
on supported rendering techniques)
signal processing (input data is a 1D signal)
images and video processing (input data is a 2D image)
small matrix operations (input data is a matrix)
operations on signals of the fixed length
g
For example, function names that begin with ipps signify that respective functions are used for signal
processing.
Name
The name element 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.
6
For example, names without modifiers: Add, Threshold, FirGenLowPass; with modifiers:
ippsFFTInv_CToC, Threshold_LT.
Intel® Integrated Performance Primitives Concepts 2
Data Types
The datatype field indicates data types used by the function, in the following format:
,
where
bit depth = <1|8|16|32|64>
and
bit interpretation[ c]
Here u indicates “unsigned integer”, s indicates “signed integer”, f indicates “floating point”, and c indicates
“complex”.
Intel IPP supports the data types of the source and destination for signal processing functions listed in the
table below.
NOTE
In the lists of function parameters, the Ipp prefix is added to the data type. For example, 8-bit signed
data is denoted as Ipp8s type. These Intel IPP-specific data types are defined in the respective library
header files.

8s
16u
16s
16sc
32u
32s
32f
32fc
64s
64f
64fc
For functions that operate on a single data type, the datatype field contains only one of the values listed
above.
If a function operates on source and destination signals that have different data types, the respective data
type identifiers are listed in the function name in order of source and destination as follows:
= [src2Datatype][dstDatatype]
For example, the function ippsDotProd_16s16sc_Sfs computes the dot product of 16-bit short and 16-bit
complex short source vectors and stores the result in a 16-bit complex short destination vector. The
dstDatatype modifier is not present in the name because the second operand and the result are of the
same type. The result is scaled and saturated.
There are several data types, namely 24u, 24s and 16f that are not supported by Intel IPP, but can be
readily converted to the supported data types for further processing by the library functions.
7
2 Intel® Integrated Performance Primitives Reference Manual, Volume 1: Signal Processing
For the unsigned 24u data, each vector element consists of three consecutive bytes represented as Ipp8u
data types. It has a little-endian byte order when a lower order byte is at the lower address. These data may
be converted to and from 32u or 32f data types by using the appropriate flavors of the Intel IPP function
ippsConvert.
For the signed 24s data, each vector element consists of three consecutive bytes represented as Ipp8u data
types. It has a little-endian byte order when a lower order byte is at the lower address. The sign is
represented by the most significant bit of the highest order byte. These data may be converted to and from
32s or 32f data types by using the appropriate flavors of the Intel IPP function ippsConvert.
For the 16f format, 16-bit floating point data (half type) can represent positive and negative numbers,
whose magnitude is between roughly 6.1e-5 and 6.5e4, with a relative error of 9.8e-4 ; numbers smaller
than 6.1e-5 can be represented with an absolute error of 6.0e-8 . All integers from -2048 to +2048 can be
represented exactly.
The figure below illustrates the bit-layout for a half number:
s is the sign-bit, e is the exponent, and m is the significand.
These data may be converted to and from 16s and 32f data types by using the appropriate flavors of the
Intel IPP function ippsConvert.
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
I
Sfs
P
Description
Operation is in-place (default is not-in-place).
Saturation and fixed scaling mode (default is saturation
and no scaling).
Operation is performed for the specified number of
vectors.
Example
ippsAdd_16s_I
ippsConvert_16s8s_Sfs
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.
Parameters
The parameters element specifies the function parameters (arguments).
The order of parameters is as follows:
• All source operands. Constants follow vectors.
• All destination operands. Constants follow vectors.
