Hello Mohammad,

You might want to consider using the option to profile a software application within the SDK. Users Guide 1165, the Zynq Embedded Design Tutorial, has instructions on how to use the profiler.

Per the Zynq Technical Reference Manual, UG585, (look at chapter 8) the global timer is a 64 bit auto incrementing timer that is clocked at 1/2 of the CPU clock rate. For most Zynq boards that would be 333 MHz.

The TRM can be found here: http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf
