Webb9 maj 2015 · 8. Clock interrupts (a.k.a. timer interrupts) occur on the order of every millisecond (typically configurable by the OS) and are used to support preemptive multitasking. Being invoked periodically, the OS can decide to allow the current task to continue running or schedule another task. A shorter 'tick' allows finer-grained allocation … Webb9 sep. 2014 · This interrupt is called a 'clock tick'. CPU counts the number of interrupts it has seen since the system has started, and returns that value when you call clock().
