自从1971年第一部微计算机 MCS-40问世从耒,微计算机的发展极其迅速,应用极其广泛,远远超过了以前的计算机。这是因为微计算机具有微型体积,价格低廉、可靠性高,使用方便,大批量生产等特点,引起了人们的兴趣。微计算机的发展和应用将给人们以智能的影响.是很有前途的。目前,以微处理机为核心的微型计算机可以分成4位,8们和16位,或分成单片、多片以及单板和多板机等。但制造厂家一般按其用途分类。(见表1)从表1中可见性能最低档的是4位机,它是面向消费的电
Since the first MCS-40 was introduced in 1971, the development of MCS has been extremely rapid and its application is extremely extensive, far exceeding the previous computer. This is because micro-computer with micro-volume, low price, high reliability, easy to use, high-volume production and other characteristics, aroused people’s interest. It is very promising that the development and application of microcomputers will give people an intelligent effect. Microprocessors that are currently at the core of microprocessors can be divided into 4-bit, 8-bit and 16-bit, or divided into single-chip, multi-chip and single-board and multi-board machines. However, manufacturers are generally classified according to their purpose. (See Table 1) From Table 1 shows the performance of the most low-4-bit machine, which is consumer-oriented electricity
