本文讨论适用于不同微处理机的模块化评价和开发系统。由于微型计算机工业的迅速发展,随之而来的是各种微处理机的销售量迅速增长。这就使得对处理机进行比较性评价工作既化钱又费时。目前,微处理机的售价还在继续下跌,并在多数情况下,评价系统的主要费用是花在诸如随机存取存贮器(RAM),只读存贮器(ROM),和输入输出设备等外围设备上。用模块化方法设计评价和开发系统有利于降低成本。由公用总线结构和可选择编址的 ROM、RAM 以及 I/O 构成的主机是评价和开发系统不可缺少的组成部分。评价一个新的处理机仅仅只要设计一块专用于该处理机的印制电路板。而这些设计又可完全或部分地用于其他类似的处理机。用这种方法评价和实施一个特定的基于微处理机的系统,既省时又省钱。
This article discusses a modular evaluation and development system for different microprocessors. Due to the rapid development of the microcomputer industry, there has been a rapid increase in sales of various microprocessors. This makes the comparative evaluation of the processor both costly and time-consuming. At present, the selling price of microprocessors continues to fall, and in most cases, the major expense of evaluating systems is spent on such things as random access memory (RAM), read only memory (ROM), and input / output Equipment and other peripheral equipment. Using a modular approach to design evaluation and development systems helps reduce costs. Hosts consisting of a common bus structure and optionally addressable ROM, RAM, and I / O are integral components of the evaluation and development system. Evaluating a new processor simply requires designing a printed circuit board that is dedicated to the processor. These designs, in turn, can be used in full or in part for other similar processors. Evaluating and implementing a specific microprocessor-based system in this way saves time and money.
