摘要
用一般时序逻辑电路的设计方法设计米里型序列检测电路中存在一些问题,在没有检测到序列时就输出了检测到信号,系统工作出现不正常。分析了存在错误输出的原因之后,提出了一种通过调整输入序列使其与时钟同步,改进状态装换表的设计,以确保系统正常工作的米里型序列检测的设计方法,这种方法有效克服了米里型序列检测的问题,并对米里型时序逻辑电路的设计有通用性。
There are some problems in the design of Mealy model sequence detection with the general design method. When the valid sequence is not detected the circuit output indicates that valid sequence has been detected,the system is abnormal. Analysed the reason of the error output,a method of designing Mealy model sequential circuits is presented,which ensures the circuit work correctly by adjusting the input sequence to synchronization with clock and reforming the state change table. Such a method effectively overcomes the problems in the sequence detection.It is applicable to general Mealy model sequential circuits design.
