Embedded system has been applied in military, electronics, munication, industrial control and so on, with respect to its small size, high performance, low cost, high reliability and oriented object program. Embedded controller with RTOS gets over the traditional microcontroller and the disadvantage of the unreal time specialty base on pc, instead it is realtime, low cost ,miniaturized ,customized ,and high dependability. It also has a broad foreground , along with the fast development of hardware of embedded system . This intention of this topic is designing the embedded system, which is important for enhancing the understanding of embedded system. The research is highlighted in both design theory and applications of embedded system, which extended its developments. This paper is anized into six parts: 1. This article essentially introduced the development of embedded system, its classification, applications in numerous areas, and its development orientation. 2. The second chapter covers the general design of the embedded system, based on the elements of embedded system design. then it shows the devise ideology and methods in either hardware or software, and the demonstration of its accessibility. 3. The third chapter gives out the hardware of the embedded system, including design, test and implementation of each module, as well as their interface circuitry. 4. The forth chapter introduces the process and attentions of RTOS 181。C/OSII, when explanted to the LPC2136 embedded controller hardware platform. 5. It covers a indept analyzing in the realtime performance in μC/OSII core, as xx 大學(xué)碩士學(xué)位論文 III well as the real time respond parameter in the very condition. 6. In the future, we will expand the operation system based on RTOS, and derivations of each module. In a word, the article provides keen insight into the platform architecture of hardware and explants of the RTOS, in addition to affording an embedded platform for the subsequence developments.
