摘要
分析环形计数器的结构特征及状态转换过程,给出了在环形计数器闭合反馈环路任何一位的位置断开环路,在次态函数卡诺图上进行激励函数逻辑修改实现环形计数器自启动设计的技术,目的是探索环型计数器自启动设计的逻辑修改技术,改进了目前的在保持右移移位寄存器内部结构不变的基础上只求解第1位触发器的激励函数的局限性设计方法,结果是简化了环形计数器的设计过程,从而使环形计数器自启动设计方法具有普遍适用性。
Analysis of ring counter in the structure characteristics and state conversion process, given the in ring counter closed feedback loop any a disconnect position loop. In the next state Karnaugh map of incentive logic function modification technology to achieve ring counter design of self-correction, It＇s aimed to explore the logic function modification of self-correction in ring counters improved the current while maintaining the right shift shift register the same internal structure based on only solving the 1 bit flip-flop excitation functions for the limitation of design method, gesign progress of ring counter is simplified,so that the ring counter design of self-correction; method has general applicability.
