Abstract


In recent years, communication technology , network technology and the rapid development of semiconductor technology and embedded technology, embedded system on human life had a tremendous impact and will continue to change people's future lifestyle. But isolated from the Internet, embedded systems no longer meet the contemporary trends. With the \make full use of network resources, to achieve a wider range of information sharing and more types of information services. Research embedded systems, an indispensable foundation work is to achieve the relevant processor embedded operating system platform on the transplant ; Meanwhile, with the network 's role in life is growing, so embedded devices to access the Internet has significance. In everyday life , through the Modem Internet is still a general way , so μC/OS- Ⅱ real-time operating system designed on a PPP agreement , in order to achieve network communication equipment , has a great significance. Based on this case , the subject was proposed based on ARM7TDMI processor μC/OS- Ⅱ operating system design and implementation of PPP . First, briefly ARM7TDMI processor hardware platform architecture and corresponding instruction set. After the analysis of the real-time operating system μC/OS- Ⅱ task management , clock management , interrupt management , memory management , inter-task communication and synchronization features for the operating system behind the PPP protocol provides the basis for the design and implementation . And the right part of the code associated with the processor and compiler was modified to achieve a μC/OS- Ⅱ in the ARM development board transplantation for the design and implementation of the PPP protocol provides a software development platform. Finally , focusing on the introduction of the system platform PPP protocol design and implementation of specific process , mainly on the main main module , LCP module , PAP module , NCP module and PPP module five aspects of design and coding . Through testing, validation of the ARM development board PPP protocol network traffic.
