Syntax

IppStatus ippsEncodeZfpInit_32f(Ipp8u*
pDst
, int
dstLen
, IppEncodeZfpState_32f*
pState

Parameters
pDst
Pointer to the destination buffer for compressed data.
dstLen
Length of the destination buffer.
pState
Pointer to the ZFP compression structure.
Description
This function initializes the ZFP compression structure. Its size must be calculated by calling the function
EncodeZfpGetStateSize
beforehand.
Use the
EncodeZfpInitLong
function 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
dstLen
is less than or equal to zero
(applies only to the
EncodeZfpInit
function
.

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.
