<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
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.
