摘 要 随着计算机技术的发展，嵌入式系统获得了越来越广泛的应用。嵌入式处理器的应用量远远超过了通用处理器，几乎在我们身边的所有电子设备中都有嵌人式系统，嵌入式应用的发展已经进入了—个全新的时期。在嵌入式应用中，ARM微处理器深受厂家的欢迎。ARM微处理器将以其极好的性能和极低的功耗与高端的MIPS和PowerPC嵌入式微处理器抗衡。可以预见，在将来一段时间内，ARM微处理器仍将主宰32位嵌入式微处理器市场。因此学习和掌握ARM微处理器技术是非常必要的，而设计ARM微处理器最小系统是非常有意义的。 本文就基于A的智能控制最小系统进行了设计。此次设计选用的芯片是LPC2378，利用ARM新能高、能耗省、资源丰富具有较强的事务管理功能等特点，进行了就最小系统的硬件和软件的构建。 硬件方面就最小系统方面进行了电源模块，复位电路模块，JTAG电路模块，存储器模块，时钟电路模块进行了设计，此外就键盘和显示屏进行了补充设计。 软件方面主要介绍了uC/OS-II。本文简单的介绍了uC/OS-II的概述和内核分析。同时移植了uC/OS-II作为系统的软件平台，编写了启动与移植相关代码。uC/OS-II作为开源的嵌入式实时操作系统，拥有极为精简的内核和出色的实时性与可靠性，作为控制单元的操作系统平台对任务进行管理与调度，从软件上保证了系统的稳定性与可靠性。 关键词：ARM微处理器；LPC2378；最小系统；嵌入式系统；uC/OS-II Abstract With the development of computer technology, the embedded system has applied more and more widely. Embedded processor is used far more than the general processor, we can find them in electronic equipment almost all around us, the application of the embedded development has entered a new era. In embedded application, ARM microprocessor is welcomed by manufacturers. With its excellent performance and low consumption the ARM microprocessor is contend with high MIPS processor and PowerPC embedded microcontroller. In the foreseeable future, in a period of time, the ARM microprocessor will still dominate 32 bits embedded microprocessors market. So study and grasp the ARM microprocessor technology is very necessary and design minimum ARM microprocessor system is very significant. This paper is designed the minimum intelligent control system based on the ARM. The design of the chip is the ARM LPC2378, which has high energy consumption, new can provinces, rich resources has strong affairs management function characteristics, we designed the smallest system hardware and software construction. The Hardware design includes the power module, the reset circuit module, the JTAG circuit module, the memory module, the clock circuit module hardware design, and adds the keyboard and screen design. Software mainly introduced the uC/OS-II. This paper simply introduces
