Large number of functions in IPP 5.3.1 IXP libraries are crashing in runtime

Hi,

We have been able to build a H.263 codec based on IPP sample code.
Running the codec, however, linked to IPP 5.3.1 libraries for IXP architecture, on both Windows Mobile 5.0 and Windows Mobile 6.0, built with VisualStudio 2005, results in code crashing in following functions:

ippiCopy_8u_C1R
ippiCopy8x8HP_8u_C1R
ippiSpatialInterpolation_H263_8u_C1R
ippiUpsampleFour_H263_8u_C1R
ippiDownsampleFour_H263_8u_C1R
ippiResample_H263_8u_P3R
ippiFilterDeblocking8x8HorEdge_H263_8u_C1IR
ippiAdd8x8HP_16s8u_C1RS
ippiDCT8x8Inv_16s_C1I
ippiDCT8x8Inv_4x4_16s_C1I
ippiDCT8x8Inv_2x2_16s_C1I
ippiScanInv_16s_C1
ippiQuantInvInter_H263_16s_C1I
ippiDecodeCoeffsIntra_H263_1u16s
ippiDecodeCoeffsInter_H263_1u16s
ippiReconstructCoeffsInter_H263_1u16s
ippiAddBackPredPB_H263_8u_C1R
ippiCopy16x16HP_8u_C1R
ippiDCT8x8Inv_16s8u_C1R
ippiReconstructCoeffsIntra_H263_1u16s
ippiAdd8x8_16s8u_C1IRS
ippiOBMC8x8HP_MPEG4_8u_C1R
ippiFilterDeblocking8x8VerEdge_H263_8u_C1IR
ippiSqrDiff16x16_8u32s
ippiSSD8x8_8u32s_C1R
ippiDCT8x8Fwd_8u16s_C1R
ippiQuantIntra_H263_16s_C1I
ippiDCT8x8Fwd_16s_C1I
ippiSubSAD8x8_8u16s_C1R
ippiEncodeDCIntra_H263_16s1u
ippiEncodeCoeffsIntra_H263_16s1u
ippiEncodeCoeffsInter_H263_16s1u
ippiQuantInvIntra_H263_16s_C1I
ippiSAD16x16_8u32s
ippiSAD8x8_8u32s_C1R
ippiMeanAbsDev16x16_8u32s_C1R

Crashes also were present in these:

ippsFree
ippsMalloc_8u
ippsMalloc_32u
ippsMalloc_32s
ippsCopy_8u
ippsCopy_16s
ippsSet_8u
ippsZero_8u
ippiCopy8x8_8u_C1R
ippiCopy16x16_8u_C1R
ippiCopy8x8HP_8u_C1R
ippiCopy8x8HP_8u_C1R

but we were able to write a substitution code.
Also to note that exactly same code built and ran under Windows XP work great.

Please give us an estimate when are these crashes will be fixed.
With best regards,
Developers

Dear Customer,

As you may notice, the samples for Intel IXP processors were tested only in Windows* CE 5.0, ( check readme from /ipp-samples/audio-video-codecs/application/simple_player/readme.htm#Running_the_Software) .. it could be some issues for the platforms wedid not test/support in the current version.

At this time, we have no plan to support other platforms for Intel IXP4xx Processors with Intel XScale technology. Please check if you can build these samples under supported platforms indicated in our release notes and readme for samples.

Hope it helps.
Thanks,
Ying
