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。
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。
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。
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。
A large number of microprocessors have interrupt system and priority logic.
大多数微处理器系统中都有一个中断系统及优先级逻辑。
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。
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)。
