Platform-Aware Functions for Image 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,
ippiAdd_8u_C1RSfs_L
.
Currently, the following image processing functions have platform-aware APIs:

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
ippi_l.h
header is included into
ippi.h
.
