Maskable interrupt sources that cannot preempt the kernel code and are thus able to invoke operating system APIs from within their handlers.

正规中断。不能抢占内核的掩码中断源，因此可以在处理程序中调用操作系统API。

Maskable interrupt sources with the ability to preempt the kernel code and thus have a lower latency and are less subject to jitter, see Response Time and jitter.

可以抢占内核的掩码中断源，因此拥有更短的延迟时间并且不容易受抖动，参考响应时间与抖动。

This paper studies the interrupt latency and context-switch time of embedded real-time operating system, and about the interrupt latency a non-maskable interrupt idea is put forward.

本文分析了嵌入式实时操作系统的两个重要的性能指标任务切换时间和中断延时及对实时控制的影响，并针对中断延时提出非屏蔽中断的改进方法。
