State Machine 又稱Finite State Machine(FSM)。State Machine 是循序電路 當中,

最全面性的一種邏 輯方式 , 如暫存器、移位暫存器、計數 器等均可以看成是一

個功能固定的State Machine。但State Machine 通常用在比較特殊的循序邏 輯電

路 中 , 用State Diagram 的方式描述方式 , 通常是一個較有系統的方法。有了 正

確的狀 態圖後 , 我們就可以依據該State Diagram 來 設計一個State Machine , 以

符合所要求的設計規格。-State Machine also known as Finite State Machine (FSM). State Machine is a sequential circuit, the most comprehensive kind of logical methods, such as registers, shift registers, namely, number of devices covered by renewable as a function of fixed State Machine. But the State Machine is usually used in a relatively special sequential logical circuit in the manner described with the State Diagram way, is usually a more systematic approach. There了 correct Shell Condition diagram, we can design future pursuant to the State Diagram a State Machine, in order to meet the required design specifications.
