Design And Implement For Embedded Software Developing Platform On Communication

Along with the broad use of the embedded real-time operation system in the field of communication, the development of the embedded software is brought more and more attention to the people. Plenty of communication products have been started to develop by adopting some embedded operation systems like VxWorks, pSOS, Linux, etc. However, comparing with Windows operating system, the embedded operating system has some characteristics e.g. difficult to study, complicated to design, perplex to be trial running etc, so it's not only more difficult to develop but also takes longer time to finally bring to the market. Thus, how to quickly impact with market, how to shorten the developing period, how to increase the stability and reliability of the products, how to lower down the difficulty of the development, how to increase the level of reuse of the different modules betweens, and how to transplant between different platforms becomes a big subject of research in current industry of communication.As per those purposes, this thesis puts forward an effective effort and attempt on the study of developing the General embedded operation system which is applied to the industry of communications. The main work of this thesis is as following:(1) One kind of theory and methodology of general embedded platform for communications (Communication Embedded Software Developing Platform, CESP) industry is proposed, which mainly includes 2 big sections, one is the branch supporting system and the other one is branch platform tools system.(2) The composition and realization of the branch supporting system is discussed, including timers realization, memory management, files management, processes communication, system scheduler and so on.(3) This study and implement shows that the development CESP on the general embedded system research platform towards to industry of communications can be realizing the transplant of productsbetween different platforms, isolation from hardware platform, cut/configuration, it is simple of 2nd development on the CESP platform and an obvious shorten on the period.
