Abstract

An executing system of a finite-state machine comprises an engine unit, a storage unit and an executing unit. The engine unit is used for receiving input events. The storage unit is used for storing the current state of the finite-state machine and a state transfer table. The executing unit is used for obtaining the current state of the finite-state machine from the storage unit and obtaining a next-state machine which needs to be transferred by a current-state machine and using the obtained next-state machine for updating the current state of the finite-state machine according to the input events provided by the engine unit and the state transfer state stored in the storage unit. The state transfer table comprises N layers of state machines, upper-layer state machines comprise a plurality of repellent lower-layer state machines, the lower-layer state machines are obtained through inheritance of the upper-layer state machines and the lower-layer state machines are provided with interface modules for entering the upper-layer state machines inherited by the lower-layer state machines. Each state machine in the N layers of state machines only has one living example and only processes the input event which is directly related to the living example. The invention further provides an executing method of the finite-state machine.

Description

technical field [0001] The invention relates to a finite state machine, in particular to an execution system and an execution method of the finite state machine. Background technique [0002] A finite state machine has a finite number of states, generally including states and transition relationships between states. In the system development of the finite state machine, the transition between states is realized by setting corresponding conditional statements according to the current state and the current input event. In this way, when the system includes a large number of states, each state intersects and affects each other during the transition process, which makes the system design more and more complicated, making the system difficult to maintain and expand. Contents of the invention [0003] In view of this, the present invention provides a finite state machine execution system and execution method that are easy to maintain and expand. [0004] An execution system of...
