一、引言 在谈到微型计算机时,必不可免地要涉及“微处理机”一词,人们常把二者混淆起来,因此有必要先了解一下它们之间的关系和区别。 微型计算机是计算机家族中继小型计算机之后最年轻的一员。虽然它具有许多突出的特点,但就基本结构来看,它和以往的计算机是大致相同的。如图1所示,图1(b)为微型计算机的组成,其中RAM(随机存取存贮器)和ROM(只读存贮器)组成了存贮器,而运算器和控制器合在一起叫微处
I. INTRODUCTION When it comes to microcomputers, it is inevitable to deal with the word “microprocessors.” People often confuse the two. Therefore, it is necessary to understand the relationship and differences between them. Microcomputers are the youngest members of the computer family to relay smaller computers. Although it has many outstanding features, but in terms of basic structure, it is roughly the same with the previous computer. As shown in Fig. 1, Fig. 1 (b) is a microcomputer configuration in which a RAM (Random Access Memory) and a ROM (Read Only Memory) make up a memory, and an arithmetic unit and a controller are combined Together called micro
