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 weled 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/OSII. This paper simply introduces the summary of uC/OSII and analysis of the kernel. While introduces the transplanting of uC/OSII as the system software platform, write a startup and transplantation code. UC/OSII as a source of embedded realtime operating system, and has an ex
