In other words, an FIQ is just a higher priority interrupt request, that is prioritized by disabling IRQ and other FIQ handlers during request servicing.
在换句话说，一个FIQ仅仅是一个更高优先级的中断请求时，由请求服务期间禁用IRQ和其他FIQ处理程序的优先级。
If high priority interrupts are not disabled during low priority interrupts, users must save the key registers in software during a low priority interrupt.
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。
These changes provide a fully preemptible kernel, threaded interrupt handlers, high-resolution timers, priority inheritance, and robust mutexes.
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）。
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.
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。
With threads, important tasks can be scheduled to take precedence over-and even interrupt-lower-priority tasks.
通过线程，可以优先调度重要任务—甚至中断—低优先级任务。
A method on expansion of multilevel interrupt priority for MCS 51 single chip computer with software is studied.
介绍了一种在不增加任何硬件的情况下用软件扩展MCS -51单片机多中断优先级的方法。
Specially, such techniques as interrupt hook, event synchronization, message passing, double frame memory alternation and priority setup are used to insure the real-time performance.
特别采用了中断挂接、事件同步、消息传递、双帧存交替以及优先级设定等技术确保图像采集的实时性。
If you are in priority drop mode, writing this number to EOI decreases the priority, writing the same value to DI will retire the interrupt (check GICC_CTLR to confirm your mode).
如果你是在优先丢弃模式，写这个号码EOI降低优先级，写相同的值di将退休中断(检查GICC_CTLR确认您的模式)。
