| With the development of Micro-Electronic technology, Embedded System is being enhanced by high-capability and low-costing hardware that decides it acceptable or not. On the other hand, all kinds of advanced thoughts once used on PC are introduced into this area, such as OO, JAVA. In fact, great potential market is the root cause of absorbing most concern and pushing it quickly.Here some features are discussed first such as application purpose, system architecture, and hardware/software environment. Basing on it, the relationship of interaction is tried to expose among them. Embedded System, as a typical application of Computer Science, is always around the core of "application-purposed". From the appearance, its specialism conflicts with the popular view that "open" and "universal" computer system architecture benefits applications. However, the truth is the union is bringing up among the field and Corp. inside.Under this condition, Field-oriented Extension of Embedded Operating System begins to be researched. Capter 2 and 3 try to answer what is Field-oriented Extension of Embedded Operating System. Further analysis on its essential and key technich is basing on the comparetion with special products.In the research on Field-oriented Extension of Embedded Operating System, focus is locked on the area of Personal Comminication Terminal. According to the basic characterics and requirements, system architecture design is provided. Much effort is put on associating the field characterics and system implement.As another attemptation, the policy of encapsulation of OS follows the standared of Microsoft COM. |
