Syntax

IppStatus ippsDecodeZfpInit_32f(const Ipp8u*
pSrc
, int
srcLen
, IppDecodeZfpState_32f*
pState

Parameters
pSrc
Pointer to the input buffer holding the compressed data.
srcLen
Length of the compressed data buffer.
pState
Pointer to the ZFP decompression structure.
Description
This function initializes the ZFP decompression structure. Before using this function, calculate the size of the structure calling the
DecodeZfpGetStateSize
function.
Use
ippsDecodeZfpInitLong
to process large 3D floating point arrays.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if any of the pointers is
NULL
.
ippStsSizeErr
Indicates an error if the parameter
srcLen
is less than or equal to zero
(applies only to
ippsDecodeZfpInit
)
.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
