I have a function that consume a specified number of
clock cycles, this number is a parameter of this
function. But in some cases the function consume a
number of cycles greater than the number in the
parameter. This problem happens at constant time
interval. I think that is the o.s. that ''preempt''
the thread when the time slice is reached. My
reasoning is correct?
Thank
