在8080和6800占支配地位的微计算机市场经过一段相对平静时期之后,Z-80微计算机系列的问世对用户产生了强烈的影响,这个第三代微计算机系列表明,微计算机的发展如同从8008进展到8080所取得的进展一样前进了一大步。Z-80系列最重要的特点是:1.GPU 和外围控制器的集成电路装置全部使用单一的5伏电源和单相5伏时钟。2.具有用自动矢量实现嵌套多级中断进行优先选择的完善的中断结构,而不需要再附 After a relatively quiet period in the 8080 and 6800 dominant microcomputers market, the advent of the Z-80 micro-computer series has had a strong effect on users, and this third-generation micro-computer series shows that micro-computers have evolved as much as 8008 The progress has been a big step toward the 8080’s progress. The most important features of the Z-80 Series are: 1. The integrated circuit device for GPUs and peripheral controllers all use a single 5-volt power supply and single-phase 5-volt clock. 2. With automatic vector nested multi-level interrupt to give priority to improve the structure of the interrupt, without the need to re-attached
