  • Sorry for not clarifying. I do mean context switch of two OS threads .

    i.e if I have two threads which were created in the non-secured world, what is the overhead in clock cycle when the context switch between them occurs? 

    also, if I have two threads, one was created in a secured world and one in a non-secured world, what is the overhead in clock cycle when the context switch between them occurs?
