Energy Profiling of an ARM7 core

Ram Prasadh
Note: This was originally posted on 8th July 2013 at http://forums.arm.com

Hi

I want to make energy profiling and analysis of a ARM7 core. I have some doubts regarding this. May be my doubts are silly.

#1 :: I don't have a development board with myself and so, I intend to make a virtual simulation of the core. I have a DS-5 community edition installed in my windows 7 system.
     Please tell me whether I would be able to do a virtual Simulation with an external hardware connected?. I came to know that about the ARMulator. Can it be invoked in the DS-5 for a virtual simulation of a ARM7.? If it can be,what should I do to use the ARMulator.? Firstly , can the DS-5 be used for the above mentioned purpose?

#2 ::  How can I test the core by using Benchmark codes like Dhrystone marking in DS-5?

Regards,
RamPrasadh N.

    So , Can I take from your words that, If I simulate a code for ARM7 in RVDS,I can get the Number of cycles of instructions for the executed code?
    Is there any other possible way to do an energy profiling for ARM7?

    I do have an other query here.

    How can I calculate the current consumption of  an ARM core by simulation.? If I have a processor running on ARM core, I may be able to dis-able all the peripherals, in software and measure the supply current through a meter. It may be approximated to the core current consumption.Correct me If I am wrong. But, will I be able to do it through simulation?
