Knowing intsructions and cache

[praveenurs]

Hi,

I am trying to profile a function (using Vtune) related to video application. The time taken by that function increaes exponetially say 40ms , 80, 50, 300, 600ms etc. My question is, "How do I know is the timing includes the intsructions and the memory accesing times".

Is there any way that I can get instructions and stalls for that perticular function.

Is there any tool find out the cache profiling.

Thanks in advance.

There is a way but it is not easy. It involves you reading the VTune documentation to learn how to use it. People here cannot do that for you.

Depending on your processor, you can select events that will give you an idea as to the number of cache misses, etc. For the Intel Core2 processor family, please see this white paper.
