The Research Of Embedded Linux Real-Time OS And Appliance In IA

Information Appliance is combinative results of computer technology , di gital communication and tradition home electrical appliance. It is research hots pot in domain of information today. Embedded Real-time Operating System issoftware kernel of supporting Information Appliance production. This thesis mostly discusses and researches key issues of constitution of Linux-based Em bedded Real-time Operating System.Firstly, this thesis summarizes constitute structure and performance special ity of ERTOS. It introduces research actuality of Embedded technology. On b ase of synthetic comparing manifold Embedded Operating System exiting tod ay, the paper analyzes excellences and limitations of using Linux constructingEmbedded System . Furthermore, It designs real-time reconstruction project o f Linux kernel for contraposing these excellences and limitations. In this thesi s ,1 construct a Embedded Linux System which contain characteristic of hard real-time , minute timepiece granularity and kernel condense and also adds op timized real-time schedule module. Lastly , I apply these innovative technolog y to Intelligence Network refrigeratory for MeiLing joint-stock Limited Compa ny and program upper application software of Network refrigeratory.
