The CPU frequency is a hardware related thing, so there's no general method that you can apply to get it, it also depend on the OS you are using.

For example if you are using Linux, you can either read the file /proc/cpuinfo or you can parse the dmesg boot log to get this value or if you want you can see how linux kernel handle this stuff here and try to customize the code to meet your need :
