【摘要】：嵌入式系统是专用的计算机系统,对于嵌入式系统的使用已经深入到社会各个领域。由于其低功耗、低成本、可裁剪的特点,被广泛地应用于工业控制领域。本文结合ARM9架构处理器和嵌入式Linux操作系统进行深入研究,提出了基于嵌入式Linux的ARM9工业控制板的设计方法。论文结合ARM9处理器与嵌入式操作系统,探讨了嵌入式系统的特点与发展方向。从工业控制板的实际需要出发,在对比了X86架构与ARM架构优缺点的基础上,选择了工业控制板所需使用的处理器；综合考虑项目需要和几种嵌入式操作系统的特点,工业控制板使用嵌入式Linux作为操作系统。完成了系统软硬件选型后,提出了工业控制板的整体设计方案。根据工业控制板的整体设计方案,实现了工业控制板的硬件电路设计,包括系统核心电路与外围电路的设计。系统核心电路设计包括SDRAM、NANDFLASH和NORFLASH。系统同时支持NANDFLASH和NORFLAHS启动,阐述了两种启动方式的区别。系统外围电路则完成了LCD、IDE、DM9000A等硬件电路的设计,并实现了基于CPLD的PC104总线。在系统软件设计方面,首先完成了系统Bootloader的开发,其次移植了嵌入式Linux的内核,最后移植与编写了驱动程序,驱动程序的开发重点是LCD, DM9000A和PC104总线驱动的移植与编写。
[Abstract]:The embedded system is a special computer system, and the use of the embedded system has gone deep into all fields of society. Due to its low power consumption, low cost, and can be cut, it is widely used in the field of industrial control. In this paper, the design method of ARM9 industrial control board based on embedded Linux is presented in detail with the research of ARM9 architecture processor and embedded Linux operating system. Combining with ARM9 processor and embedded operating system, this paper discusses the characteristics and the development of the embedded system Starting from the practical need of the industrial control board, on the basis of comparing the advantages and disadvantages of the X86 architecture and the ARM architecture, the processor to be used by the industrial control board is selected, the characteristics of the project need and several embedded operating systems are comprehensively considered, and the industrial control board uses the embedded Linux as the operation system. After the software and hardware selection of the system is completed, the whole design party of the industrial control board is put forward. According to the overall design scheme of the industrial control board, the hardware circuit design of the industrial control board is realized, including the system core circuit and the peripheral circuit. The system's core circuit design includes SDRAM, NFLAMSH and NORFL. ASH. The system supports both NFLASSH and NOFLAHS start-up, and describes the two ways of starting The peripheral circuit of the system completes the design of hardware circuits such as LCD, IDE, DM9000A, and implements the PC10 based on CPLD 4. In the aspect of system software design, the development of the system Bootloader is first completed, and then the kernel of the embedded Linux is transplanted. Finally, the driver is transplanted and written. The development of the driver is the driving of the LCD, DM9000A and PC104 bus.
