Hi Sky,
Fortunately, you come to the right place:)
Our JPEG2000 codec Linux sample supports IXP425 processors. That means that even in spite of the fact that there is no WMMX optimization in IPP JPEG2000 functions, codec can be used on PXA270 processors as well. Please visit IPP Samples Page to download JPEG sample. Note, you also need to get IPP for IXP for Linuxin order to be able to build this sample.
Regards,
Vladimir

Hi Sky,
We not released WinCE v4.0 for Xscale version of JPEG2000 sample because there is limitation in STL(standard template library) support in MS EVC v4.0. We use STL mostly in implementation of errors and warnings reporting. If you want to port this sample on WinCE by yourself, you need to download IPP for IXP libraries and headers. It provides simple more-less direct mapping you are looking for.I did not say just direct mapping because IPP for IXP does not provide functions for Ipp32f and Ipp64f data types due to target architecture limitation.
Regards,
Vladimir

Hi Sky,
I mean you can use IPP for IXP. It does not contains WMMX optimization, but it contains all the functions needed for JPEG2000 codec. We have sample for linux which you can try to use

1>dsubband.obj : error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@)
Is there anything tricky I have left out? May I know if there is any significant difference between the ia32 and the ixp library? Any sugguestions or walkaround to this problem?
Many thanks,
Yin

Hi Yin,
yes, MSeVC v4.0 SP2 has limited support for STL (or even do not have it at all). So, it probably to difficult to port this sample to WinCE, but we provide JPEG2000 sample for MontaVista Linux on IXP for both little-endian and big-endian arhitectures.
The main difference between IPP for IA and IPP for IXP is limited support for Ipp32f and Ipp64f data types in IPP for IXP because of target platform has no hw match co-processor.

Vladimir

Hi, Vladimir,
Thanks for the reply! However, I will still be using Windows for development. Is that possible to work directly with the linux example sourcecode under windows?Is thereany neccessary modifications that I have to made if I use IPP for IXP under Windows?
Many thanks,
Yin

Actually I am using VS2005 and pocketpc 2003 SDK. It compiles but got linker errors. Currently I only linked with the set of static libraries found in IPP IXP, could it be a problem?

No, I don't think linkage model is a problem. Unfortunately we do not tested sample on WinCE
