Signals are software interrupts that send information about an occurrence of an asynchronous event to an executing program, or process.
信号就是软件中断，可以向正在执行的程序(进程)发送有关异步事件发生的信息。
The RTSJ includes support for handling asynchronous events triggered by a number of sources including timers, operating-system signals, missed deadlines, and other application-defined events.
RTSJ包含了对异步事件处理的支持，触发异步事件的事件包括大量包含计时器的源代码、操作系统信号、超过时限和其他应用程序定义的事件。
Due to the asynchronous nature of signals, it is difficult to point out the bug caused when a signal-handling function triggers a non-reentrant function.
由于信号在本质上是异步的，所以难以找出当信号处理函数触发某个不可重入函数时导致的bug。
Events relate asynchronous "externalities" to programmed callbacks (also called signals, bindings, and so on).
事件将异步的“外部动作”与编程上的回调(也称为信号、绑定等等)联系起来。
Asynchronous interrupts are generated by other hardware devices at arbitrary times with respect to the CPU clock signals.
异步中断是由其他硬件设备产生的，可以在CPU时钟信号的任意时刻到来。
This paper introduces a useful method to realize asynchronous acquisition of multi-channel signals on AT87C51 single-chip microcomputer using software timers.
本文介绍了一种利用软件定时器在AT87C51单片机上实现多路信号异步采集的实用技术。
Because DSP is the core of the system, asynchronous serial signals could be acquired directly.
DSP作为系统核心，使得本系统能直接采集异步串行数字信号。
