Have to use performance Monitors (for bench Marking) on Hardware?

Note: This was originally posted on 11th May 2009 at http://forums.arm.com

Hi all,

I want to do benchmark my application in ARM Cortex A8. For that one i have downloaded some bench mark code using performance monitors from ARM website (see below link) .

[url="http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka4237.html"]http://infocenter.arm.com/help/index.jsp?t...aqs/ka4237.html[/url]

Basing on the procedure provided in the above link i am bench marking my code in Cortex A8 using ISSM but it is giving zero... Even if i Used RTSM also it is giving very less value i.e., 0.8 MIPS... but same appication if i run on ARM Work bench profiller it is giving 28 MIPS...

Is performance counters i have to use in Hardware or what?

Please help me to do benchmarking a function with out using profilling but using performance monitors or other way?

Thanks in Advance.
