IPP library for Mobile Platforms

SergeyKostrov — Wed, 30 Nov 2011 22:53:13 GMT

Are there any plans to release a version ofIntel IPP library (at least some domains ) for aMobile Platform?

A complete list of Mobile Platforms could be as follows:

Android
Symbian
iOS
BlackBerry
Windows Mobile
Windows Phone 7

Best regards,
Sergey

Windows Mobile was supported (is supported) in IPP versions 5.0 -> 5.3 (IPP version for IXP for win).
Guess that these versions (IXP for Linux) may compatible with listed above *ux - derived OSes.
Also all latest versions of IPP (ia32 for Linux) are compatible with x86 Android.

Igor,

Sime time agoyou posted IPP's'IppCpuType' enumeration and I don't see asupport for Intel XScale, or
ARMx, or SHx CPUs.

Microsoft stated that these CPUs are supported by a Windows Mobile x.xoperating system. Also, in Visual
Studio 2005\2008 I don't see a support for Intel XScale CPUin case whenI work with a Smart Device
project.

Is there an Intel's document that clearly confirms this? By the way, where did you findor read about IPP library for Windows Mobile?

Thank you in advance.

Best regards,
Sergey

I found lots of posts on Intel Software Networkregarding the subject ( it was popular! ).

You are correct in that the standard prebuilt libraries for Pocket PC 2003 are ARMV4 based, whereas
XScale has additional features and is basically ARMV5TE compliant (which is really a superset of ARMV4
and thus you don't have any compatibiulity issues).

The way to oprimize for XScale is to select an ARMV4 platform in VS2005 and then either
...
use the Microsoft Compiler with the additional options /QRxscale /QRxscalesched removing any options
that refer to ARMV4 compatibility

The MS Windows hosted Intel C++ Compiler v1.2 for XScale does not support building Linux applications
at this point

I'll try to continue my search on Marvell's website some time later. At the moment, it is clear that in our
case, that issoftware developmentfor Windows Mobile platforms,another solution has to be considered
instead of using IPP library for XScale CPU.

It would be nice to see a complete list of supported CPUs.

Thank you.

Sergey,

I've taken a look at the ippdefs from the 5.x version - yes, it doesn't have XScale in the list - but it was not required asIPP library for ixp didn't use any dispatching mechanism - it was special library for any arm-compatible cpu without any simd extensions support.

Igor
