Finite State Machines in Hardware: Theory and Design (with VHDL and SystemVerilog) (The MIT Press) [Volnei A. Finite state machines (FSMs) are at the heart of most digital design. A finite state machine, in its most abstract form, is a device that accepts a set of inputs, maintains a current state, and, based on the inputs and the current state, produces outputs and a new state when it encounters a clock edge. The machine word opcode is used as the index into the table, and the various control signals are output to the respective destinations. Mason, Michigan State University. A state machine will change state dependent upon its current state and also current factors impacting the system, namely, inputs.

Finite State Machines in Hardware: Theory and Design (with VHDL and SystemVerilog) (The MIT Press) [Volnei A. Finite state machines (FSMs) are at the heart of most digital design. A finite state machine, in its most abstract form, is a device that accepts a set of inputs, maintains a current state, and, based on the inputs and the current state, produces outputs and a new state when it encounters a clock edge. The machine word opcode is used as the index into the table, and the various control signals are output to the respective destinations. Mason, Michigan State University. A state machine will change state dependent upon its current state and also current factors impacting the system, namely, inputs.
