I am working on PXA27X family processor from MARVEL,I have few test cases to test on this processor
The place where i am struck is changing the main clock frequency run time. since PXA27X Process does support clock frequency up to 520MHz. But best working frequency set is 312MHz.
I am working on power management where have an game application & i have an algorithm to calculate the total clock cycles/sec required for each frame and for this time calculation also i am using main clock this some times gives me wrong result
I wanted to configure an external clock or there is 32.786KHz clock(OS Timer) supports up to resolution 1 milliseconds and want to use this clock as reference clock
I wanted to know whether changing the main clock frequency on the run effects this external/CLK_32 clock or not?
Any kind of help is appreciated
Thanks in advance
