IPP for StrongArm

calvin0905 — Thu, 08 Dec 2005 02:11:49 GMT

Hi,

IPP 3.0 used to support StrongArm processors (no DSP instruction set as in xScale). In one project I still need to compile for strongArm, what are the options I have. I spent the whole day looking for IPP 3.0 for the strongArm processor but I could only find the PDF documentation.

Can I use any of the XScale IPP libraries with a processor without the DSP IS? If not, is the IPP 3.0 still available some where.

Thanks in advance.

Calvin.

Hi Calvin,

if your question is about IPP for Xscale without WMMX you can use IPP for IXP. It is available in IPP v5.0

Hello Vladimir,

Thanks for your reply. My question actually takes the technology even one step behind the WMMX. As far as I know, the XScale is an ARM V5TE compatible core and the StrongArm is a simple ARM V4 compatible. This means the StrongArm does not implement the thumb instruction set (T) and does not have the 40-bit accumelator and the instruction supporting it (E). This makes the StrongArm code run on the XScalebut not the other way around.

Now I need to fix an older product that runs on the StrongArm and used the IPP, but I can not find this IPP library any where any more.

Can you provide me with that IPP for StrongArm or a replacement?

Thanks again.

Calvin

I recommend you to contact with Intel Premier Support to try to solve this issue.
