ConvolveGetBufferSize

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

Syntax

IppStatus ippsConvolveGetBufferSize (int
src1Len
, int
src2Len
, IppDataType
dataType
, IppEnum
algType
, int*
pBufferSize
);
Include Files
ipps.h
Parameters
src1Len
Number of elements in the first source vector.
src2Len
Number of elements in the second source vector.
dataType
Data type for convolution. Possible values are
ipp32f
and
ipp64f
.
algType
Bit-field mask for the algorithm type definition. Possible values are listed in the
IppAlgType
enumerator.
pBufferSize
Pointer to the size of the work buffer.
Description
The
ippsConvolveGetBufferSize
function computes the size, in bytes, of the external work buffer needed for the functions that perform convolution operations. 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 the length of the vector is negative, 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.
ippStsDataTypeErr
Indicates an error when the
dataType
value differs from the
ipp32f
or
ipp64f
.

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.
