I am having a baremetal program running on a ARM cpu which is processing interrupts of a real time application. Power is also a constraint, so i am thinking of playing with the frequency of that particular CPU. Is there a way with which i can predict the change ( in interrupt latency or the jitter in the interrupt latency) i can expect when i change the frequency. I know i can do this manually by implementing it and measuring it, but i would like to know whether there is a logical or mathematical way to do this.
Thanks.
