BWTGetSize_SmallBlock

Computes the size of the external buffer for the BWT transforms for small data block.

Syntax

IppStatus ippsBWTGetSize_SmallBlock_8u(int wndSize, int* pBuffSize);

Parameters

wndSize	Window size for BWT transform.
pBuffSize	Pointer to the computed size of the additional buffer.

Description

The function ippsBWTGetSize_SmallBlock is declared in the ippdc.h file. This function computes the size of memory (in bytes) of the external buffer that is required for the forward and inverse BWT transforms of the small data block by the functions ippsBWTFwd_SmallBlock and ippsBWTInv_SmallBlock respectively. The size of the data block must be in the range (0, 32768].

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if pBuffSize pointer is NULL.
ippStsSizeErr	Indicates an error if wndSize is less than or equal to 0, or is greater than 32768.
