ippiAdd for Ipp32s

[ezeng3]

HI, All:

     I cannot find the ippiAdd for data type Ipp32s, even in the latest ipp2019 update 3. Is there any specific reason and what is the work around solution?

    Thanks.

Best Regards,

Edwin Zeng

Hi Edwin,

the simplest workaround is to use ippSP functions - for each image row:

IPPAPI(IppStatus, ippsAdd_32s_ISfs,  (const Ipp32s*  pSrc,                        Ipp32s*  pSrcDst, int len, int scaleFactor))
IPPAPI(IppStatus, ippsAdd_32s_Sfs,   (const Ipp32s*  pSrc1, const Ipp32s*  pSrc2, Ipp32s*  pDst,    int len, int scaleFactor))
IPPAPI(IppStatus, ippsAdd_32sc_ISfs, (const Ipp32sc* pSrc,                        Ipp32sc* pSrcDst, int len, int scaleFactor))
IPPAPI(IppStatus, ippsAdd_32sc_Sfs,  (const Ipp32sc* pSrc1, const Ipp32sc* pSrc2, Ipp32sc* pDst,    int len, int scaleFactor))

Hi, Igor:

       Thanks for your information. Yes, I have tried to use ippsAdd, but it is much slower compared to directly using the SIMD instruction.

        Is there any specific reason why the intel does not provide the ippiAdd for the 32s? It provides the function to allocate the memory, but there is no much basic operation to support the Ipps32 for image.

Best Regards
