Platform-Aware Functions in Signal and Data
Processing
Intel® Integrated Performance Primitives (Intel® IPP)
library provides so-called platform-aware functions. These functions use the
special data type
IppSizeL
for object sizes. The
IppSizeL
data type represents memory-related
quantities: it can be 32- or 64-bit wide depending on the target architecture.
While the rest of Intel IPP functions support only objects of 32-bit
integer size, platform-aware functions can work with 64-bit object sizes if it
is supported by the platform. The API of platform-aware functions is similar to
the API of other Intel IPP functions and has only slight differences. You can
distinguish platform-aware functions by the
L
suffix in the function name, for example,
ippsMalloc_16u_L
.
Currently, the following signal processing functions have platform-aware
APIs:
Function Group
| Header
| Function Name
|
---|---|---|
Support Functions
| ipps_l.h | Malloc |
Intel IPP platform-aware functions are documented as additional flavors to
the existing functions declared in standard Intel IPP headers (without the
l
suffix). The
ipps_l.h
header is included into
ipps.h
.
