BWTFwd_SelectSort

Performs the forward BWT transform with specified sort algorithm.

Syntax

IppStatus ippsBWTFwd_SelectSort_8u(const Ipp8u* pSrc, Ipp8u* pDst, Ipp32u len, Ipp32u* pIndex, Ipp8u* pBuff, IppBWTSortAlgorithmHint sortAlgorithmHint);

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.
pBuff	Pointer to the additional buffer.
sortAlgorithmHint	Specifies what sort algorithm is used, possible values:
	ippBWTItohTanakaLimSort; ippBWTItohTanakaUnlimSort; ippBWTSuffixSort; ippBWTAutoSort.

Description

The function ippsBWTFwd_SelectSort is declared in the ippdc.h file. 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 parameter sortAlgorithmHint specifies the desired algorithm of sorting. The function uses the external buffer pBuff. The size of this buffer must be computed by calling the function ippsBWTFwdGetBufSize_SelectSort beforehand.

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.
