【摘要】 本文探讨了一种基于EDA(电子设计自动化)技术的周期可变、脉宽可变的脉冲发生器,具体采用的EDA技术是针对Altera公司生产的复杂可编程逻辑器件(CPLD),通过软件编程,对硬件结构和工作方式进行重构,使硬件设计如同软件设计那样。为解决CPLD器件工作控制的限制,提出了采用单片机控制CPLD器件的动态配置技术,文章分析了以INTEL公司的MCS-51单片机器件和Altera公司MAX7000系列器件为例的组合模式CPLD动态配置的原理和实现。更多还原

【Abstract】 The paper mainly discusses a EDA technology based signal generator which has changeable period and pulse-width. The kind of EDA technology we pratically used corresponds to the CPLD which made by Altera . Through software programming , we can reconstruct the structure of the hardware and working mode which makes the hardware designing exact the same as software programming. To solve the limit of CPLD’s working control, we put forward the dynamic configuration technology which adopt CPLD controlled by SCM . This paper analyzes the theory and relizationg of combined-mode CPLD’s dynamic configuration ,and take MCS-51 SCM made by INTEL and MAX 7000 series made by Altera.更多还原
