毕业论文（设计）基于S3C2440平台的μCOS实时操作系统的移植说明书.docVIP

摘 要 μC/OS-II操作系统是专门为计算机的嵌入式应用设计的, μC/OS-II 具有执行效率高、占用空间小、实时性能优良和可扩展性强等特点。 因而广泛应用于各种嵌入式控制系统中。本设计论文阐述了μC/OS-II操作系统在S3C2440硬件平台上移植的实现方法, 分析了其基本原理, 给出了实现过程。 随着ARM技术的广泛应用，建立基于ARM构架的嵌入式操作系统已成为当前的研究热点。本课题的研究内容就是将μC/OS-II移植到包括2个头文件,用来配置事件控制块的数目以及是否包含消息管理相关代码. 而与处理器相关的移植代码部分则是进行移植过程中需要更改的部分,包括1 个头文件OS CPU.H ,1 个汇编文件OSCPU_A.S 和1个C代码文件.实际上将C/OS-II移植到ARM 处理器上,需要完成的工作主要是以下三个与体系结构相关的文件:OSCPU.H ,OS_CPU.C以及OSCPU_A.S。 本设计在ADS 1.2编程环境中编译μC/OS-II操作系统在S3C2440硬件平台上运行成功。最后编写了多线程测试程序进行测试。 关键词：；；；1 ABSTRACT μC/OS-II operating system is designed specifically for embedded computer applications design, μC/OS-II has the implementation of high efficiency, small footprint, real-time performance and scalability, strong. Thus widely used in a variety of embedded control systems. This design introduces S3C2440 hardware platform transplant μC / OS-II operating system implementations, analysis of its basic principles, given the realization of the process. With the wide application of ARM technology, the establishment of the ARM architecture-based embedded operating system has become a hot spot of the current study. This topic is the use of transplantation technology uC/OS-II ported to ARM system. UC/OS-II ported to ARM system can be combined with the advantages of both. The key to the design of the study is to rewrite the μC/OS-II operating system code, including rewriting the main file including 2 header files used to configure the number of event control block and whether it contains the message management code. Associated with the processor the the porting code part need to change in the transplant process, including a header file OS CPU.H of the assembly file OS_CPU_A.S and a C code file. actually uC/OS-II ported to ARM processing on the need to complete the work is the the three architecture file: OS_CPU.H, OS_CPU.C, as well as OS_CPU_A.S. This design based on ADS 1.2 programming environment based on the basic principles of μC / OS-II operating system, the design S3C2440 hardware platform
