<p>Intel designed performance monitoring hardware into the XScale.  They 
also have a profiling tool called VTune that consists of some "data 
collector" code running on the XScale target, and a windows host 
application that collects the data from the target and displays it 
graphically, etc.


But the web site says it targets the DBPXA250 development board 
(containing a PXA250) running one of the several Windows CE variants, so 
it might not be useful to you.  Plus they charge for it.

I've never used this tool, but I have used a VTune version for profiling 
Pentium code.  It's pretty good, quickly highlighting the performace 
hotspots for you.  Too bad they didn't make the XScale version more 
general-purpose and put the code in the public domain.
