如果在响应低优先级中断时高优先级中断使能，用户必须在低优先级中断响应程序中保存那些关键的寄存器值。
If high priority interrupts are not disabled during low priority interrupts, users must save the key registers in software during a low priority interrupt.
中断到达与分发必需任务之间的时间(假设分配的是优先级最高的任务)称为响应时间。
The time between the arrival of the interrupt and dispatching of the required task (assuming it's the highest-priority task to dispatch) is called the response time.
这些更改提供了完全抢占式内核、线程中断处理程序、高分辨率计时器、优先级继承和健壮的互斥锁（mutex）。
These changes provide a fully preemptible kernel, threaded interrupt handlers, high-resolution timers, priority inheritance, and robust mutexes.
