Research Of Embedded System Design Method Based On ARM

Now, the embedded application system, represented by information appliance, is leading embedded system to booming development. It will make the information technology industry get more development, and bring far-reaching influence to people's production and life. The developing of embedded system contain two parts, universal embedded system and above application program development. Researcher or company don't need develop entire hardware and software of embedded system; can develop the embedded system on the basic of developed system, shorten exploitation periods,and promotes own product promptly, increased the market competitive power.This paper's topic is to set up a platform of embedded system, and then develop object oriented application software design method based on the platform.Firstly, the paper fetched out a typical, real-time and multitasking embedded operating system:μC/OS-II, gave a detailed analysis on the embedded operating system kernel structure and kernel realization method.Secondly, according to the demand ofμC/OS-II transplant, the paper designed and developed a hardware experiment platform that the hardcore is a 32-bit MCU S3C44B0X of Samsung Company, realized theμC/OS-II transplant. And,introduced the debug method and the configuration of debug setting in the chapter.Then, used the embedded operating system on control of furnace temperature, realized theμC/OS-II multitasking dispatching by that platform, and made a contrastive research with the software design method of traditional fore-back ground type. Give out the validity of using RTOS.At last, finished the design of TPMS based on embedded operate system. This system's theory foundation is based on large numbers of experimentation data and references, and the paper finished the whole frame design,softwaredesign based on RTOS, ultimately passed the primary software test. And at the end of chapter, gave an analysis of error and applicability. It is the further application based on ARM+μC/OS-II, and proved out the advantage.
