A: Fundamentals of Single-chip Microcomputer
The single-chip microcomputer is the culmination of both the development of the digital computer and the integrated circuit arguably the tow most significant inventions of the 20th century [1].
These tow types of architecture are found in single-chip microcomputer. Some employ the split program/data memory of the Harvard architecture, shown in Fig.3-5A-1, others follow the philosophy, widely adapted for general-purpose computers and microprocessors, of making no logical distinction between program and data memory as in the Princeton architecture, shown in Fig.3-5A-2.
In general terms a single-chip microcomputer is characterized by the incorporation of all the units of a computer into a single device, as shown in Fig3-5A-3.
单片机是电脑和集成电路发展的巅峰，有据可查的是他们也是20世纪最有意义的两大发明。
这两种特性在单片机中得到了充分的体现。一些厂家用这两种特性区分程序内存和数据内存在硬件中的特性，如图3-5A-1，依据同样的原理广泛的适用于一般目的的电脑和微电脑，一些厂家在程序内存和数据内存之间不区分的像Princeton特性，展示如图3-5A-2.
只读存贮器(ROM). ROM是通常的永久性的，非应用程序的易失性存储器。不少微机和单片机用于大批量应用，因此，经济的设备制造要求的程序存储器的内容是在制造期间永久性的刻录在芯片中，这意味着严谨的方法，因为修改ROM代码不能制造之后发展。这一发展过程可能涉及仿真,使用硬件仿真功能以及强大的软件工具使用先进的开发系统。
