题目

英语翻译
单片微型计算机简称单片机,是典型的嵌入式微控制器（Microcontroller Unit）,常用英文字母的缩写MCU表示单片机.单片机比专用处理器更适合用于嵌入式系统,因此它得到最多的应用.对于单片机来说,复位电路是必不可少的部分.无论我们使用哪种类型的单片机,总是要涉及到单片机复位电路的设计.而单片机复位电路设计的好坏,直接影响到整个系统工作的可靠性.本文通过对单片机的常用复位电路进行分析,总结了各种复位电路的使用环境和优缺点并加以改进.还注重讨论了单片机复位电路的抗干扰性和复位时间方面的内容,最后还设计了一款基于常用复位芯片的看门狗复位电路.

答案

Single Chip Micro-computer is called Single Chip for short,which is a typical Embedded Microcontroller Unit,and is usually abbreviated as MCU.MCU is more suitable to be used in embedded systems than dedicated processors,and it gets most of the applications.For an MCU,Reset Circuit is an essential part.No matter what kind of MCU we use,the design of its reset circuit is always revolved.Moreover,quality of the design will directly affect reliability of
the whole system.This article summarizes and gives an improve on the environments for use,the advantages and disadvantages of various reset circuits,with a good analysis for common uesd reset circuits.It also puts importance on the discussion of noise immunity and time limit of Single Chip reset circuits.In addition,it has proposed a degign of reset circuit,which is called "watchdog" and is based on common reset chips.
