BWTFwd
Performs the forward BWT transform.
Syntax
IppStatus ippsBWTFwd_8u(const Ipp8u* pSrc, Ipp8u* pDst, int len, int* pIndex, Ipp8u* pBWTFwdBuff);

Libraries: ippcore.lib, ippvm.lib, ipps.lib
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. |
