AutoCorrNormGetBufferSize

Computes the size of the work buffer for the
ippsAutoCorrNorm
 function.

Syntax

IppStatus ippsAutoCorrNormGetBufferSize (int
srcLen
, int
dstLen
, IppDataType
dataType
, IppEnum
algType
, int*
pBufferSize
);
Include Files
ipps.h
Parameters
srcLen
Number of elements in the source vector.
dstLen
Number of elements in the destination vector (length of auto-correlation).
dataType
Data type for auto-correlation. Possible values are
ipp32f
,
ipp32fc
,
ipp64f
, or
ipp64fc
.
algType
Bit-field mask for the algorithm type definition. Possible values are the results of composition of the
IppAlgType
 and
IppsNormOp
 values.
pBufferSize
Pointer to the size of the work buffer.
Description
The
ippsAutoCorrNormGetBufferSize
 function computes the size in bytes of the external work buffer needed for the function that performs auto-correlation. The result is stored in the
pBufferSize
 parameter.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
 is
NULL
.
ippStsSizeErr
Indicates an error when
srcLen
 or
dstLen
 is less than, or equal to zero.
ippStsAlgTypeErr
Indicates an error when:
  • the result of the bitwise AND operation between the
    algType
     and
    ippAlgMask
     differs from the
    ippAlgAuto
    ,
    ippAlgDirect
    , or
    ippAlgFFT
     values;
  • the result of the bitwise AND operation between the
    algType
     and
    ippsNormMask
     differs from the
    ippsNormNone
    ,
    ippsNormA
    , or
    ippsNormB
     values.
ippStsDataTypeErr
Indicates an error when the
dataType
 value differs from the
ipp32f
,
ipp32fc
,
ipp64f
, or
ipp64fc
.

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.
