| 术语 | delta clock |
| 释义 | delta clock δ时钟,再启动时钟 A clock whose primary use is timing subroutine operations. If a momentary fault throws the computer into a closed programming loop, or if a fault occurring during the execution of an instruction halts the computer, the delta clock restarts the computer by means of an interrupt, thus providing automatic fault recovery. The interrupt can be programmed to notify the operator that a closed loop has occurred. If completing an operation takes longer than desired, this clock is also used to interrupt the computer and thereby allow program attention to be diverted to items of more immediate importance. 一种主要用途为定时子程序操作的时钟。如果暂时的故障导致计算机进入死循环,或者 如果在执行指令期间发生故障而使计算机暂停的话,再启动时钟就通过一个中断重新启动计 算机。因而提供了自动的故障恢复手段。可对该中断编程,以便通知操作员已出现死循环。 如果完成一个操作花的时间比要求的时间长,也可以利用该时钟来中断计算机,把程序注意力 转移到更重要的方面。 |
