A FSM-based implementation of event control system under embedded environment

The radio software is a typical kind of the embedded environment software.Generally the firmware's architecture consists of three parts: VRIS level,common signaling layer and user interface layer.The high layer(user interface layer) is the event flow control center of the whole radio software and the kernel part of it is effective,reliable and expandable.A FSM(finite state machine)-based control system implementation is introduced.This technology is used in the radio firmware and the result shows that it is a very effective method.
