Hi all,
I am new to cortex m3...
For my application I need to calculate the number of cycles for a particular function....
I set the debug options as high optimization level and optimize for time....
How can I calculate the MIPS/cycles manually for a particular function.
Please suggest me a solution...
Thanks in advance.
Krish.

so we can access the DWT only by connecting the board?
I tried like this but did not work....
Not sure if this part of DWT is modelled in ISSM. Did you follow the initialisation procedure in the Cortex-M3 TRM?
Regards
Marcus
