基于状态机的报文检测器设计

The Message Detector Based on State Machine

本文首先介绍了报文检测器的基本功能,基于状态机的设计思想具有灵活多变,通用性高等优点,将状态机原理引入到报文检测器中,通过FPGA仿真实现,可以得到,基于状态机设计的报文检测器能够识别出两种形式的报文,即便两种报文的报文头一致,也完全可以区分,最终实现了优化报文检测器的目的。

This paper firstly introduces the basic function of message detector, and then adopts the design idea of state machine, which is flexible and versatile, so the theory of state machine is introduced into the message detector.Through the FPGA simulation, we can receive that the designed message detector can identify two types of messages,even if the headers of the two messages are consistent. Ultimately, we realize the purpose of message detector＇s optimization.
