【摘要】 在FPGA(现场可编程门阵列)器件设计中,状态机的设计方法是最常用的设计方法之一,而通过怎样的编码形式才能达到最好的设计要求,成为设计所要解决的一个很重要的问题。在状态机的编码方式中,最常用的是顺序编码和One-hot编码方式。文中通过对这两种状态机编码方式的优缺点比较,说明应该如何选择编码方式,以及如何避免在此过程中可能出现的一些错误。更多还原

【Abstract】 For the design of programmable logic device,the design method of FSM is one of the more important design methods.It is a very important problem which encoding style we use would make our design to achieve optimum result.Sequential encoding and one-hot encoding are in common use in all the encoding styles.In this article,by comparing the disadvantages and advantages of these two encoding styles we explain how to select encoding style and how to avoid the default that may appear.更多还原
