Parameters
pSrc
Pointer to the source vector.
pDst
Pointer to the destination vector.
len
Number of elements in the source and destination vectors.
pIndex
Pointer to the index of first position for the forward BWT transform.
pBWTFwdBuff
Pointer to the additional buffer.
Description
This function performs the forward BWT transform of
len
elements starting from
pIndex
element of the source vector
pSrc
and stores result in the vector
pDst
. The function uses the external buffer
pBWTFwdBuff
. The size of this buffer must be computed by calling the function
ippsBWTFwdGetSize
beforehand.
Code example  shows how to use the function
ippsBWTFwd_8u
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error if
len
is less than or equal to 0.

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.
