The Research Of μC/OS-Ⅱ Port For ARM

With the development of computer technology, The Embedded system has become a important constituent in computer domain, and became the recent years emerging research hot spot. The ARM microprocessor used as hardware foundation and μC/OS-Ⅱ used as Embedded operating system is been widespread in a lot kinds of Embedded application system. This paper introduces arm microprocessor and μC/OS-Ⅱ firstly, and discusses and researches the project for the μC/OS-Ⅱ port for ARM microprocessor, which essential technology was elaborated by realization code ; and proposed in transplant process had to pay attention question. This paper to μC/OS-Ⅱ task stack processing carried on the detailed analysis, and proposed 3 improvements ways reduced the memory the amount of use. If μC/OS-Ⅱ want to realize network function ,must support the TCP/IP agreement.This paper through realized the TCP/IP agreement stack to the LwIP transplant; Through compiled 8019 networks actuations finally realizes the network function.The simulation work is carries on through Skyeye completes.
