有限状态机(Finite State Machine, FSM)是一种用于描述系统行为的数学模型,它由一组有限状态和状态之间的转移规则组成。有限状态机在工程、计算机科学和数学中广泛应用,用来表示和分析具有离散状态的系统。 有限状态机的组成 有限状态机通常包含以下要素: 状态集(States): 系统中可能的所有状态的集合。例如,一个简单的...

Build a finite-state machine that searches for the sequence 1101 in an input bit stream. When the sequence is found, it should set start_shifting to 1, forever, until reset. Getting stuck in the final state is intended to model going to other states in a bigger FSM that is not yet im...

有限状态机(Finite-State Machine,FSM),又成为有限状态自动机,简称状态机,是表示有限个状态以及在这些状态之间的转移和动作等行为的数学模型。笔者常在电机控制、通信协议解析等应用场景下应用FSM。 本文所讲的是基于硬件描述语言Verilog HDL的有限状态机的编写技巧及规范。众所周知FPGA以其并行性和可重构性为世人所知...

FSM(Finite State Machine)是数字设计中经常涉及到的部分。FSM分为两类:Mealy型和Moore型,其主要区别是:Mealy型状态机的输出与当前状态和输入均有关;Moore型状态机的输出仅与当前状态有关,而与输入无关。 如何设计有效的状态机,避免一些不希望出现的输出结果(如锁存、毛刺等),是本文的谈论要点。
Finite state machine (FSM) is one of the first topics taught in any digital design course, yet coding one is not as easy as first meets the eye. There are Moore and Mealy state machines, encoded and one-hot state encoding, one or two or threealwaysblock coding styles. Recently I was ...
