The Research And Realization Of Embedded System For Internet Media Player(IMP)

In recent years, with the rapid development of computer technologyand communication technology, and especially the integration of 3C(computer, communicate, consume electric), micromation and specialize-tion are becoming the new trend and embedded products will play themost important role in IT industry. Therefor, the integration products ofembedded systems and network will become the favorite of people.This paper is based on the project of Internet Media Player (IMP) inwhich the author worked as an intern in a company to participate. Itmainly discusses the key technology of IMP embedded system, including:1. The summary of IMP embedded system. The first part of the thesisintroduces functional definition, system structure of IMP andembedded system overview.2. System design overview and the establishment of software andhardware platform. This part introduces the two major components ofIMP embedded system: IMP client and the control center software.The development platform is based on the embedded Linux OS,MC9328MX21 microprocessor, Qt for graphical user interface.3. The design and realization of IMP. This part introduces the basicfunction and structure of IMP especially the description of design andrealization of four component modules including agent module,browser module, embedded BT module and UI(User Interface)module based on QTE(Qt Embedded).4. Communication protocol. This part introduces the communicationprotocol format, related code tables of IMP and control centersoftware.5. Control center software. This part introduces the function, features ofcontrol center software especially the description of design andrealization of various component modules.The research results have been applied to the IMP embedded system.It is proved that the processing method proposed in this thesis is feasiblein practice and IMP has good social and economical benefits.
