一位微处理器在国内外都是继八位机之后研制出来的产品。它属大规模集成电路的低档产品,但价格便宜、装置体积小、编程简单、扩充容易,采用CMOS工艺,耗电少。考虑到微机的应用原则是采用最少的必要器件设计制作一个系统而不减小它的功能,所以在小容量或中容量陆地移动电话系统中,尤其对于移动站,采用一位微处理器实现信号控制是很适宜的。在中容量移动电话的信号系统中,一位微处理器起着指挥部的作用,它接受信号系统中 A microprocessor at home and abroad are following the eight machine developed products. It is a low-end large-scale integrated circuit products, but the price is cheap, the device is small, simple programming, easy to expand, the use of CMOS technology, low power consumption. Considering that the principle of application of the microcomputer is to design a system using the minimum necessary components without reducing its function, a microprocessor for realizing signals in a small-capacity or medium-capacity land mobile telephone system, especially for a mobile station Control is very suitable. In the signal system of a medium-capacity mobile phone, a microprocessor functions as a command unit that accepts signals from the signal system
