【正文】 許多時鐘電路，還具有電阻和低電容工作成本定時元件，也可以從外部源驅動。這將緩解重新加載計數(shù)器和評估所用的時間，計時器重新啟動之前這是必要的。這可以由每個程序中的執(zhí)行時間分支認真評估，但除最簡單的程序外，他的工作效率不高。串行輸入/輸出。中央處理單元（CPU）(十進制處理（BCD）的數(shù)據(jù)為例）數(shù)字顯示，因而，常?？梢园l(fā)現(xiàn)該CPU是很適合處理這種類型的數(shù)據(jù)。EPROM（可擦除可編程只讀存儲器）插座或存儲器，而不是ROM器件。這一發(fā)展過程可能涉及仿真,使用硬件仿真功能以及強大的軟件工具使用先進的開發(fā)系統(tǒng)。這兩種特性在單片機中得到了充分的體現(xiàn)。 EPROM(Erasable programmable ROM )sockets or devices with EPROM instead of ROM 。英文文獻翻譯學 生 姓名劉學毅專 業(yè)自動化學 號0833141分 院電子工程分院2012年 6 月1. 外文原文 A: Fundamentals of Singlechip Microputer The singlechip microputer is the culmination of both the development of the digital puter and the integrated circuit arguably the tow most significant inventions of the 20th century These tow types of architecture are found in singlechip microputer. Some employ the split program/data memory of the Harvard architecture, others follow the philosophy, widely adapted for generalpurpose puters and microprocessors, of making no logical distinction between program and data memory as in the Princeton architecture, shown in .In general terms a singlechip microputer is characterized by the incorporation of all the units of a puter into a single device.Read only memory (ROM) ROM is usually for the permanent, nonvolatile storage of an applications program .Many microputers and microcontrollers are intended for highvolume applications and hence the economical manufacture of the devices requires that the contents of the program memory be mitted permanently during the manufacture of chips . Clearly, this implies a rigorous approach to ROM code development since changes cannot be made after manufacture .This development process may involve emulation using a sophi
