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

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.

    Hi,

       Thanks for ur fast reply, 

       If i used performance Monitors to find bench mark information in Hardware, is it will give correct information or not?

       Is it correct way or is their any way to find the benchmark information in Hardware?

      I want to do all this for Cortex A8?
