calculation of execution time from the clock cycles

Hello all,

I have been working with zed board and I have code written for matrix multiplication and is running on the ARM, I have got the clock cycles in a similar way as mentioned in the app note XAPP1170.

I am trying to calculate the execution time.

SoI am trying to do it using the following formula execution time = No of clock cycles X time period

(OR) execution time = No of clock cycles / frequency

I am wondering which frequency needs to be taken into account Is it the processor clock frequency or clock frequency of the timer i.e FLK_CLK0 (100MHz). All settings of clock are defaut and my processor is running at 666.6667MHz and the timer is running at 100MHz (FLK_CLK0).

any help would be greatly appreciated.

Thanks
Dinesh.
