In this paper, the concepts of embedded system, embedded system architectures, manifold factors to be considered when designing the system, the application prospects of embedded system are studied. We set the design and development of Internet Application (Network Game Online) an example to introduce the flow charts, experiences, and questions that should be paid attention to when we developing the software on detail.There are four components in Network Game Online System?Microwindows subsystem, asynchronous transfers with buffers network subsystem, interface subsystem based microwindows, core data structure processing routine subsystem.Mierowindows is GUI running under Linux operating system, and we can get resource codes free. This system mainly finished three layers of windows system?bottom Driver Layer, middle Engine Layer, upper API Layer.Asynchronous Transfers with Buffers Network Subsystem is bottom support module.Interface Subsystem Based Microwindows implemented the interfaces of this system, including: actualization of windows, actualization of control unit, actualization of application operation (keyboard, mouse, infrared equipment), actualization of display of interface and hint of information. This system is the most upper module of this project.Core data structure processing routine subsystem is the middle layer of this project. As for key module, it can analyze and process data to actualize the function of system. At the same time, it can call and harmonize the other layers.In conclusion, this paper shows the data flow charts, design methods, actualization of aboveentioned parts in detail.
